Presently the door of his cell was thrown open and a seaman appeared carrying a bowl of hot soup.

"Can I have my clothes dried?" asked Alec.

"It's not my work to dry the clothes of a schweinhund," replied the fellow in English. Then he pointed to the Sub's wristlet watch.

"For that I will dry your things," he added.

"Right," replied Alec. "It isn't going, though. The water's spoilt it."

"That is to be expected," rejoined the German, picking up the saturated garments. Then waiting until Alec had handed over his watch, he went out, to return presently with a canvas suit, rust-marked and greasy.

"In case Herr Kapitan sends for you," explained the man, and without another word he again backed out of the compartment and locked the door.

While waiting for the soup to cool, the Sub, with feelings of repugnance, put on the loaned suit. It felt damp and clammy and smelt vilely. As for the soup it was little better than dish-water, greasy and unpalatable, while with deliberate intent an excessive quantity of salt had been put into the liquid. Nevertheless Alec took a considerable quantity, for he was desperately famished, and the hot concoction warmed his chilled body, for even in the warm atmosphere cold chills were persistently passing over him.

For several hours—how long Alec had no accurate idea—the U-boat ran submerged. As far as he could estimate it was about noon when she came to the surface, only to dive again very quickly, to the accompaniment of a couple of bombs from a British sea-plane. Although wide of the mark the explosion of the missiles gave the submarine a nasty shaking up, so much so, that the startled Huns allowed their craft to rest on the bed of the North Sea until nightfall before resuming their course.

It was during this period of enforced detention that Alec was summoned to be examined by Kapitan-leutnant von Kloster.
