way off the road, silhouetted against the night sky, the jagged outline of a crumbling tower and below it a huddle of uneven roofs. Leaving the road, they followed a winding path through some tall bushes until they came out into a small clearing adjacent to one side of the ruin. The light was just sufficient for them to make out a low, arched doorway mid-way between two arrow slits. Stepping up to it, Khurrem grasped an iron bell-pull and jerked it down. A bell jangled hollowly somewhere inside the ancient ruin. Almost at once the heavy door swung open and a swarthy hunchback of uncertain age silently ushered them in.
Without exchanging a word with him she led them down a dimly-lit stone-flagged passage and opened another heavy door on the right at its end. Momentarily they were dazzled, for the room into which they followed her was brightly lit by a big, solitary, incandescent mantle which, from its faint hissing, appeared to be powered by some form of gas.
The burner stood on a large desk in the middle of the room.Behind it a man was sitting, but the bright light prevented his visitors from making out his features until he stood up and came forward. They then saw that he was tall and gaunt, looked to be in his late fifties and had a marked resemblance to Khurrem; but his hair was black flecked with grey, his nose more hooked but thinner, his complexion darker and his full mouth more sensual. His eyes were black and slightly hooded, but his smile was pleasant as Khurrem said, â
Herren
, this is my father, Dr. Ibrahim Malacou.â
âMajor Bodenstein.â The doctor held out his hand to Gregory. âI congratulate you on your safe arrival here. In our unhappy country it is a great joy to welcome men like yourself and your friend Mr. Sabinov who have the courage to come to our assistance in outwitting the evil men in whose hands Germanyâs future now lies.â
When he had also shaken hands with Kuporovitch, and Gregory had made a suitable reply, he motioned them to chairs, then went on, âMy daughter has told me that our report about the experimental work at Peenemünde reached those for whom it was intended and that as a result you have been sent to secure more detailed particulars. That will not be easy; but in your endeavours I hope to aid you. Although I live mainly as a recluse I have certain means which are not at the disposal of others by which I can smooth your path. For one thing I have a far larger-scale map of the areas in which you are interested than any you can possibly have seen and a careful study of it will certainly repay you.â
As Dr. Malacou finished speaking he stood up and, turning, pointed to the wall behind him. Gregory had already noticed that, whereas the two sides of the room were lined with shelves of old books, the far one was blank except for two large maps. While Khurrem remained seated, Gregory and Kuporovitch joined her father in front of the maps as he went on:
âThat on the left is of the von Altern property; the one on the right delineates the northern half of the island of Usedom. On it you will see marked the fords by which the creek separating it from the mainland can be crossed at low water. One moment, though. I will adjust the light so that you can see better.â
While they remained standing within a foot of the wall he stepped back behind them. Next moment his voice rang out sharp and imperative.
âDo not move! I have you covered. Put your hands up above your heads. I have dealt with spies before, so I shall not hesitate to shoot if you disobey me. Khurrem, they are certain to be armed. Relieve them of the temptation to play us any tricks by depriving them of their weapons.â

A Strange Interrogation
Gregory and Kuporovitch knew that the doctor could have stepped back no more than two paces behind them. They were two to one and by whirling round there was a fair chance that one of them could grab his pistol and force it downwards,
