The Heights of Zervos Page 8

  'Of course not! That was part of Hahnemann's job...'

  'Any idea which arm of the service they're attached to?'

  Burckhardt felt himself go very cold. Until this unnerving interview he had assumed that the two Englanders were only on board by chance, but now the Abwehr man was raising diabolical possibilities. 'Ford, the staff-sergeant, is an ammunition examiner,' he said slowly.

  Had Dietrich detected the note of reluctance in his voice? He pressed the colonel for further information instantly. 'And the other man, the so-called lieutenant - Prentice?'

  'He is with the Signals Corps.'

  'Ah! So undoubtedly an expert wireless operator...' Dietrich shrugged his shoulders, his devastating point made. He puffed at his cigar for several seconds and then said something equally disturbing. 'Since we know they have been in Turkey for several weeks it seems an even stranger coincidence that they should choose this particular trip for returning to Greece. Don't you agree?'

  'Several weeks? You know this? Is this why you are on board?' Burckhardt took a step towards Dietrich who regarded him without replying. 'They were supposed to have been saved from a ship which sank off the Turkish coast a few days ago...'

  'What ship?' Dietrich pounced on the statement. 'Is this the story they have told you?'

  'Yes, when Lieutenant Hahnemann was questioning them...'

  'He has Intelligence training, this Hahnemann?' The ironic note was back in Dietrich's voice.

  'No, but he is clever and he said their story rang true. The lieutenant — Prentice - told him this...'

  'I have seen this British lieutenant,' the Abwehr man replied slowly and deliberately, 'and I would say he not only has his wits about him - he is also capable of making up a convincing story on the spur of the moment. I don't like the way the situation is developing, Colonel Burckhardt. You should have the two Englanders questioned again.'

  Burckhardt's expression was remote. Under other circumstances, without the enormous responsibility of the expedition resting on his shoulders, he might have thought differently, and he had no way of knowing that he was confronted by a master of the art of psychological aggression. Without realizing it, he had been subjected to a kaleidoscope of changing impressions and anxieties from the moment he had entered the cabin, and during this ordeal he had subconsciously accepted the Abwehr man's credentials at face value. In fact, the subject of the identity of Dietrich had subtly been turned into questioning the identity of the British prisoners. He was also becoming a little worried about his own position. Had this devil been put aboard the Hydra to check up on the operation because it involved a naval phase - the seizure of the Hydra and its subsequent voyage to their objective! 'I'll get Hahnemann to have another word with the prisoners,' he said crisply.

  'This Prentice, he speaks German, then?' Dietrich was staring through the porthole again as he asked the question.

  'Not so far as I know - but Hahnemann speaks excellent English. I must leave for the bridge now.' He was talking again to Dietrich's back as the Abwehr man used his hand to smear a hole in the steamed-up glass. The temperature was probably at least thirty degrees higher inside the cabin than on the high seas.

  'Did Hahnemann find out anything else when he was interrogating the prisoners?' Dietrich went on peering intently through the porthole and something in his attitude made the colonel wait a few seconds longer.

  'I believe there was some mention of a British destroyer being in the area, but I'm convinced he was bluffing.'

  'Bluffing!' Dietrich straightened up, swung round abruptly. 'First you talk about it being a coincidence that those men are aboard and now you hope he was bluffing! I'm afraid a very serious situation has arisen - a strange vessel is coming in fast from the north-east and unless I'm very much mistaken it is a British destroyer.'

  Burckhardt turned to go quickly, and when Dietrich was left to his own devices he had, by default, been granted the privilege to roam round the vessel as freely as he wished.

  Burckhardt was leaving the cabin when he very nearly collided with Hahnemann who was rushing down the companionway. Halting abruptly, the soldier saluted and spoke breathlessly. 'There's an emergency, sir. Lieutenant Schnell would like to see you on the bridge - it's very urgent...'

  'I know!' Burckhardt was already pushing past him, heading for the staircase. Hard-faced young men of the Alpenkorps, fully uniformed, pressed themselves against the companionway wall with their rifles at their sides to let him pass. One man hastily extinguished a cigarette under his boot. The doorways to the three cabins recently occupied by the German passengers were open and inside more men of the Alpenkorps sat on the floors and leaned against the walls, their faces tense as they watched their colonel pass. The grapevine had worked already, reporting the rumour that a British destroyer was approaching fast. The whole atmosphere of the Greek ferry had changed, had become more akin to that of a troopship. Dodging round kit piled in the passage, Burckhardt made a mental note to get that shifted and then leapt up the staircase. Pushing open the door at the top he received a blast of cold wind and a douche of icy spray full in the face. Without even bothering to wipe himself he glanced quickly along the deserted, wave-washed deck. All the troops were under strict instructions to remain below decks and he was satisfied with the outward appearance of normality. Strange how the sea seemed far worse up here than down below. The thought flashed through his mind as he went into the wheelhouse.

  Inside the enclosed area everything was quiet and there was a feeling of disciplined control, but under the silence Burckhardt sensed an atmosphere of nerves tautly strained as the Hydra ploughed on through mounting seas. Lieutenant Schnell of the German Navy, wearing inconspicuous dark trousers and a dark woollen sweater, was holding the wheel while the ferry's captain, Nopagos, stood a few feet away with a signalling lamp in his hands. Behind him, crouched on his knees out of sight, an Alpenkorps soldier held a machine-pistol trained on the captain's back.

  'Over there. To starboard.' It was the helmsman who had spoken, nodding his head towards the north-east. Schnell was a typical German naval officer, round-faced, his dark hair neatly trimmed, a man of thirty with watchful eyes and a steady manner. Taking in the situation at a glance, Burckhardt accepted a pair of field-glasses from another soldier whose uniform was covered with a civilian raincoat. To starboard a slim grey silhouette was bearing down on the Hydra, a silhouette with lights at her masthead. Burckhardt focused the glasses on the ship and his lips tightened. Yes, it was a British destroyer sailing on an oblique course which would take her across the bows of the ferry within a mile or two. He handed back the glasses and moved into the shadows in case other glasses were aimed in his direction from that distant bridge. They wouldn't be able to pick out individuals yet, but within a few minutes they'd pick up all the detail they wanted if the destroyer maintained its present course. He spoke quickly to Schnell. 'What is Nopagos doing with that signalling lamp in his hands?'

  'He will have to use it in a minute...'

  'I don't like that.'

  'We have no alternative.' Schnell had half-turned round to stare at the oncoming warship. 'She is bound to signal us, so tell the Greek I understand the use of signals at sea.'

  Burckhardt thought quickly. It was a damnable situation: the very existence of the expedition now depended on the signal-lamp in the hands of a Greek whose ship had just been shanghaied from under him. He saw the knuckles of Schnell's hands whitened under the overhead light as he gripped the wheel and steadily kept to his course. Still crouched on the floor, the Alpenkorps soldier with the machine-pistol moved gently with the sway of the ship, his face drawn with tension as he watched Burckhardt and then transferred his gaze to Nopagos' back. Burckhardt maintained his outward appearance of calm confidence, his hands thrust into his coat pockets, although inwardly his nerves were screwed up to fever pitch. He began speaking to Nopagos in his careful, Teutonic-sounding Greek.

  'The British destroyer may start signalling. If that happens you onl
y use your lamp when I give the order. I want you to understand this clearly - the man at the wheel is a German naval officer thoroughly conversant with signalling procedures. He will be watching. If you make any attempt to send a distress signal, we shall know. If there is an emergency we shall engage the British destroyer and we shall undoubtedly be sunk. I hope you realize that it is unlikely anyone will be saved in seas like this...' Without putting it in so many words he managed to convey that Nopagos' crew were hostages. He had just finished speaking when the moonlit wake of the oncoming destroyer became clearly visible. A few seconds later the door to the bridge opened and Dietrich came inside. Burckhardt swung round and turned away again when he saw who it was. Completely unruffled by his reception, the Abwehr man walked across to join the colonel after glancing at the approaching destroyer.

  'It's probably just a routine check,' he remarked, 'but let's hope they are not expecting a signal from their friends locked up below.'

  A nerve jumped by the side of Burckhardt's neck underneath his collar. Dietrich had hardly arrived before voicing the most alarming suggestion at this critical moment. He had just quietened his mind after the Abwehr man's remark when the door burst open again and Hahnemann strode onto the bridge with a furious expression. He had hesitated to stop Dietrich following Burckhardt up to the bridge but now felt he should keep an eye on him. Burckhardt turned on him instantly. 'Hide that gun you bloody fool - they may be watching the bridge. And while you're here - had either of those British soldiers any means of signalling in their possession?'

  'No signalling lamp,' Hahnemann reassured him quickly. 'They definitely had no signalling equipment of any kind. The lieutenant, Prentice, had a revolver under his pillow. But nothing to send a message with.'

  Burckhardt glanced at Dietrich with an expressionless face, but the Abwehr man was still studying Hahnemann, who glared back at him defiantly. 'And no torch?' Dietrich queried in a deceptively mild tone. 'Not even a pocket torch?'

  Hahnemann looked confused. He started to answer Dietrich, then his face stiffened and he addressed Burckhardt. 'One of them had a torch, yes, sir. It was inside the pocket of his coat hanging up behind the door.'

  Dietrich caught Burckhardt's glance and he lifted his eyebrows in an expression of foreboding, then frowned at Schnell who had turned to say something. 'Here it comes, sir. They've started.' Across the swelling Aegean where the waves were growing higher a light began to wink on and off from the destroyer. Schnell bad half-turned to starboard, his eyes fixed on the flashing lamp which went on with Its brief explosions. On the bridge no one moved or spoke as all eyes were fixed hypnotically on the signalling light and Burckhardt could feel the stillness of men suspended in a state of horrible anticipation. So much depended on the next few minutes but Burckhardt had no intention of surrendering, whatever happened. He had had some experience of the devastating fire a British destroyer could lay down; in Norway he had seen a German troop transport reduced to a burning hulk by only a few salvoes. What those four-inch guns might do to the hull of the Hydra was something he preferred not to contemplate. The lamp stopped flashing and Schnell spoke.

  'We are asked to identify ourselves.'

  Burckhardt stood up a little straighter and gave Nopagos his instructions in Greek. 'Signal that we are the Greek ship Hydra. Nothing more. And remember that Lieutenant Schnell is a naval officer.'

  The tension on the bridge was becoming almost unbearable, like a physical affliction. Nopagos wiped his lips and glanced behind to where the Alpenkorps man gazed straight at him, the muzzle of the machine-pistol aimed at the small of his back. Burckhardt nodded confidently without speaking, as much as to say get on with it. The captain adjusted his cap and started to flash the lamp while Schnell watched him coldly, his hands still on the wheel. To the colonel it seemed to take an age to send the short message. Was marine signalling really so complicated? Was Nopagos managing to trick Schnell while he inserted a desperate SOS among the jumble of flashes? A dozen appalling possibilities ran through his mind but he could do nothing but wait, hoping that his threat had struck home to the Greek. The lamp stopped flashing. Nopagos mopped the back of his neck with a coloured handkerchief as Schnell addressed Burckhardt over his shoulder.

  'He has identified us simply as the Hydra, ownership Greek. Nothing more.'

  With a supreme effort Burckhardt resisted the impulse to let his shoulders relax; both the Alpenkorps soldiers kept glancing towards him for reassurance. German soldiers, Burckhardt had noticed before, were never entirely happy at sea - the existence of the British Navy probably had something to do with their lack of enthusiasm for water-borne expeditions. He watched the destroyer still moving on her oblique course. Would her captain be satisfied with that signal? Just a routine check, Dietrich had suggested. But a moment later he had raised the unnerving suggestion that the two British soldiers might have been put on board deliberately - that the destroyer out there was expecting another flashing signal from a porthole confirming that all was well aboard the Hydra. Blast the Abwehr!

  'They're signalling again!' Schnell spoke quietly, his eyes on the distant flashing light which was now less than a quarter of a mile away. Burckhardt stood quite still, resisting the impulse to pace up and down the bridge: it was vital at this moment to preserve an absolute outward calm. He felt that his feet had been glued to the deck for hours and God knew there were enough signs of tension on the bridge already. The signal lamp in Nopagos' hands wobbled slightly - if he had to carry on answering these bloody questions much longer he was going to crack. The soldier crouched behind the Greek captain was sweating profusely, his forehead gleaming from the light over the bridge. Hahnemann was lightly tapping a nervous fingernail on the butt of his machine-pistol and Burckhardt wanted to roar at him for God's sake stop it! Schnell, a highly experienced naval officer, was still holding the wheel tightly. All these little details Burckhardt took in automatically while the lamp on the British destroyer blandly went on flashing its message. Only Dietrich seemed undisturbed, almost at ease as he stared at the ceiling with the unlit cigar motionless in the centre of his mouth. He dropped his eyes and caught the colonel watching him.

  "There is a Greek called Grapos aboard,' Dietrich commented. 'I think he could be dangerous if he isn't watched carefully.'

  'I dealt with him myself,' said Hahnemann in a flat tone. 'He was sleeping in the saloon - he had no cabin - and I was able to knock him out before he knew I was there. He's tied up in one of the holds.' The endless strain of waiting had neutralized his natural dislike of the Abwehr man and he looked at Dietrich without resentment.

  'I do have this ship under control,' Burckhardt added icily.

  'Perhaps it might be better if I went below,' Dietrich said almost amiably. He glanced to his left and saw that Hahnemann was leaving the bridge as a cloud of spray broke over the bows of the Hydra. When the lieutenant had gone there was a loaded silence as the light from the destroyer continued flashing, the ferry's engines went on throbbing heavily, and the sea heaved endlessly under them. After the winking light had stopped, Schnell cleared his throat twice before speaking. 'They wish us to report where we're from, our ultimate destination and the time of arrival.'

  Without hesitation Burckhardt rapped out more instructions in Greek. 'Tell them we're bound from Istanbul, that our destination is Katyra, Zervos, and our estimated time of arrival 05-30 hours.' Nopagos blinked, glanced again at the sweating soldier behind him, took a firmer grip on the lamp and began signalling. The gun muzzles of the destroyer could be clearly seen in the moonlight as the vessel remorselessly continued on course without altering direction by as much as a single degree. Burckhardt found it unnerving - why was all this interest being shown in an ancient Greek ferry which spent its life plying between Istanbul and the remote peninsula of Zervos? He kept a tight grip on himself as Dietrich's rumbling voice spoke again behind his back. 'I'm wondering now whether this signalling isn't a smoke-screen put out until they get close to us. If they were expectin
g their own private signal from the prisoners below the course they are maintaining would make sense - they would keep on that course until they fired the first shot across our bows. Ten minutes should tell us the worst.' And having fired this last shot across the colonel's bows he quietly left the bridge and went out on deck.

  Tight-lipped, Burckhardt heard him go, relieved that at long last the Abwehr man was leaving the bridge. But secretly Burckhardt agreed that Dietrich's estimate was just about right. In the next ten minutes they should know the worst.

  CHAPTER FIVE

  Sunday, April 6

  As he struggled in the darkness with the ropes which bound his wrists. Prentice was bathed in sweat from his exertions. He lay in his bunk sprawled on his side, his ankles also tightly bound together while a further length of rope joined his wrists to his ankles, a rope drawn up so tautly that his knees were permanently bent. The fact that they had thought of turning out the cabin lights didn't help him either; it meant he had to work blindly by feel and this made ten times more difficult a task which already seemed insuperable. And because his hands were tied behind his back he had soon given up the attempt to fiddle with the knots he couldn't see, and a little later, when it struck him that they had probably used Alpenkorps climbing rope, he gave up his efforts to break the cords by stretching his wrists against them - a rope which could support a man dangling from a cliff face was hardly likely to weaken under the mere pressure of two straining wrists. So it seemed hope-lejs: a rope which couldn't be broken and which couldn't be untied. There was, however, one other alternative. Prentice was thin-boned and he had unusually slim wrists, so now he was concentrating all his strength on compressing his hands into the smallest possible area and then trying to pull them upwards through the loops which imprisoned him. His success to date had fallen rather short of the milder achievements of Houdini and for a few minutes he stopped struggling while he rested.
