For answer Sinclair drew an envelope from his pocket. John recognised the colour and shape of the envelope in a minute. He read the short, typed letter with gathered brows, then struck a match and destroyed it carefully. The letter contained an order from Dacent Smith that John should surrender his position at Heatherpoint to Captain X., and was to resume work immediately against Cherriton, Dr. Voules, and Mrs. Beecher Monmouth.

"It's rough luck, old chap," said Captain X., "but I expect that before this big movement is finished you will have as much chance of adventure as I shall."

"I hope so," said John. "But I was looking forward to the result of 'Crumbs's' signal. Last night the moon shone out of pure cussedness."

Captain X. sprang up to the window and looked out.

"It's clouding up to-night, old chap," he exclaimed joyously, "and you'll be away for the fun. Hallo!" he said. His eyes were lowered and were fixed upon a man in shirt-sleeves in the doorway opposite. "Is that 'Crumbs'?"

"Yes," said John, "but don't let him see you looking at him. I am not so sure that he hasn't spotted something."

"He'll spot something in a day or two," said Captain X., coming back from the window, "and in the meantime the Chief's orders are to leave him a long rope."

John's orders from his Chief were that he should report to Colonel Hobin and leave Heatherpoint immediately. He began to change his clothes, and talked to his companion at the same time.

"You can rub acquaintance with 'Crumbs' while I get out of the fort," he said. "He mustn't see me in mufti. I shall spend a night in Newport, and call on Dr. Voules to-morrow morning."

"Who do you think Voules is?" asked the Captain.
