John shook his head.

"I shall know more about that to-morrow," he said.

When he was ready to go he shook hands cordially with his companion. He always felt older than Captain X., though their ages were the same. Captain X.'s audacity and joy in life amused John. His colleague always put so much zest into everything he did.

"I should advise you," he said, gripping the Captain's hand, "to use Ewins if you want any help on the beach to-night. He is an old soldier, and I should think, if an awkward moment arrived, you could rely on him."

"Thanks," said Sinclair. "This is a new game for me. I have never had the chance of angling for a German submarine commander before, but I expect there'll be one ashore here to-night, eh, Treves?"

"Somebody comes ashore," responded John, "and reads those signals."

He went out and sat in the mess-room for a few minutes, leaving Sinclair time to occupy "Crumbs'" attention while he slipped away from the fort.

CHAPTER XV

The situation at Heatherpoint was exactly to the liking of Captain Sinclair. He realised, from what John had told him, that "Crumbs" was no mean antagonist, and he was feverish to make the spy's acquaintance. But the manner in which he strolled into "Crumbs's" bakehouse before John's departure was the most casual in the world. One of Sinclair's chief gifts was an innocent and infectious smile, and under the most trying of circumstances he was always cheerful. With this smiling cheeriness of manner Sinclair possessed, as is often the case, a fair share of astuteness.

"It smells good in here," he said, putting his head into "Crumbs's" warm atmosphere.
