Only through the broken thermantidote in King's compartment no wet air came. Hyde knelt on King's berth and wrestled with it like a caged animal, but with no result except that the sweat poured out all over him and he was more uncomfortable than before.

"What are you looking at?" he demanded at last, sitting on King's berth. His head swam. He had to wait a few seconds before he could step across to his own side.

"Only a knife," said King. He was standing under the dim gas lamp that helped make the darkness more unbearable.

"Not that robber's knife? Did he drop it?"

"It's my knife," said King.

"Strange time to stand staring at it, if it's yours! Didn't you ever see it before?"

King stowed the knife away in his bosom, and the major crossed to his own side.

"I'm thinking I'll know it again, at all events!" King answered, sitting down. "Good night, sir."

"Good night."

Within ten minutes Hyde was asleep, snoring prodigiously. Then King pulled out the knife again and studied it for half an hour. The blade was of bronze, with an edge hammered to the keenness of a razor. The hilt was of nearly pure gold, in the form of a woman dancing.

The whole thing was so exquisitely wrought that age had only softened the lines, without in the least impairing them. It looked like one of those Grecian toys with which Roman women of Nero's day stabbed their lovers. But that was not why he began to whistle very softly to himself.

Presently he drew out the general's package of papers, with the photograph on the top. He stood up, to hold both knife and papers close to the light in the roof.

It needed no great stretch of imagination to suggest a likeness between the woman of the photograph and the other, of the golden knife-hilt. And nobody, looking at him then, would have dared suggest he lacked imagination.

If the knife had not been so ancient they might have been portraits of the same woman, in the same disguise, taken at the same time.

"She knew I had been chosen to work with her. The general sent her word that I am coming," he muttered to himself. "Man number one had a try for me, but I had him pinched too soon. There must have been a spy watching at Peshawur, who wired to Rawal-Pindi for this man to jump the train and go on with the job. She must have had him planted at Rawal-Pindi in case of accidents. She seems thorough! Why should she give the man a knife with her own portrait on it? Is she queen of a secret society? Well—we shall see!"

He sat down on his berth again and sighed, not discontentedly. Then he lit one of his great black cigars and blew rings for five or six minutes. Then he lay back with his head on the pillow, and before five minutes more had gone he was asleep, with the cold cigar still clutched between his fingers.
