'He may be armed,' Hahnemann protested.
'Of course I am armed,' Dietrich replied swiftly, anticipating Burckhardt's next question. A lesser man than Colonel Heinz Burckhardt might have felt annoyance, but the colonel had risen to command an elite arm of the Wehrmacht and he had a grudging appreciation of an independent attitude. 'I am going to take out a Luger pistol,' Dietrich explained, staring at Hahnemann as though he doubted his ability to grasp plain German, 'so kindly keep a hold on yourself – and your weapon.' Producing the pistol from his coat pocket, he laid it on the table. 'It is fully loaded, incidentally – I never bluff when I have to use a weapon, which, fortunately, is a rare occasion.' The sight of the regulation pistol, a minor point, subtly reinforced Burckhardt's growing interest in the huge German passenger. For a moment Hahnemann hesitated whether to pick up the gun, but Dietrich's attention was so clearly concentrated on the colonel, was so obviously no longer aware of his presence, that he felt at a loss and glanced at Burckhardt for instructions.
'Leave us,' the colonel told him brusquely. 'I shall be on the bridge in a few minutes.'
Dietrich waited until the cabin door had closed and then stood up slowly. The action startled Burckhardt, who was six feet tall; he had realized that Dietrich also was a tall man but now he was able to see that the German civilian stood two to three inches above him. Rarely impressed by another man's physique, Burckhardt found himself a little overawed by the formidable figure who stood before him with his shoulders hunched and his hands clasped behind his broad back. Dietrich waited a moment, then put a hand inside his coat, extracted something and dropped it on the table. 'My papers, Colonel
Burckhardt.'
With a mounting sense of irritation Burckhardt looked at the card carefully, glancing up to find Dietrich watching him without any particular expression. 'You're an archaeologist, I see, Dr Dietrich?' He couldn't keep the flatness out cf his voice: he had suspected that this passenger was someone important from Berlin; it was the only explanation for his arrogant manner.
'Look at them carefully,' Dietrich urged him gruffly. 'See anything unusual about them?'
'No!' Burckhardt replied after a second perusal and there was a snap in his voice now.
'Good!' Dietrich lifted his shoulders and towered over the colonel as he went on with withering sarcasm. 'I was travelling aboard a Greek ferry which might at any time have been stopped and searched by a British destroyer. Under those conditions would you really expect me to present them with papers showing I am a senior officer of the Abwehr?'
Burckhardt stood quite still and his heart sank. Here was the explanation for Dietrich's overbearing attitude since he had entered the cabin. God, the Abwehr! That damned Intelligence organization of the incredibly influential Admiral Canaris. They never told anyone what they were going to do – not until they had done it. And they never told anyone where they were going until they had been there and arrived back in Berlin. They were responsible to no one except the wily old admiral who had started his career with naval Intelligence, and who was now answerable only to the Fuhrer himself. The Abwehr was disliked – feared might be a better word – by all the regular Intelligence services because it lived a life of its own, but even more because of its legendary record of coups. In some uncanny way the admiral managed to be right every time in his forecast of enemy intentions. Oh yes, Burckhardt had heard of the Abwehr, but this was the first time he had met one of them. That is, assuming Dietrich was who he claimed to be… He looked up suspiciously as something else landed on the table.
'Now you can see what I would have dropped through the nearest porthole if we had been stopped – along with the Luger, of course.'
Dietrich's tone was ironic, close to sneering, and Burckhardt caught the tone and felt the blood rush to his head, so for a short time while he examined the second card Baxter had doctored and handed over in Giurgiu, his normally ice-cold judgement deserted him. Dietrich walked across the cabin to look out through the porthole, still talking over his shoulder.
'You will require absolute proof of my identity, so you had better send a wireless message to Berlin. I can give you the signal code.'
'Not while we are at sea,' Burckhardt rapped out. 'We must preserve radio silence at all costs.'
'I had assumed that,' Dietrich retorted brusquely. 'I meant after you had gone ashore. You have dealt with the two Englanders, I hope?'
'Yes, Hahnemann dealt with the whole operation most efficiently. They are only a lieutenant and a sergeant travelling home from Turkey.'
'You knew then beforehand that these two men were being put on board?'
Burckhardt paused, staring at the back of the Abwehr man who continued gazing out to sea. There was something in the way the question had been phrased which disturbed him, which made him delay his departure for the bridge. Had there been some awful slip-up somewhere? 'Knew?' he repeated warily.
'Yes, "knew", I said. Did you know?' Dietrich had swung round and was talking with his cigar in his mouth, his legs splayed as he continued to dominate the conversation.
'No,' the colonel admitted reluctantly. 'I was worried when I first heard about them but they are of very junior rank…'
'Are you certain of that? Papers can be easily forged or doctored – including army pay-books. These two men could be far more important for all we know.' He paused to give his insidious suggestion maximum impact. 'They could be on board because some hint of your operation has reached the Allies. You may be lucky they never reached the wireless-room.' He leaned forward grimly. 'I take it they did not reach the wireless-room?'
'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.
