The figure, evidently satisfied that no one was watching, walked briskly down the street, and Harry's heart beat hard against his side. He knew that it was Shepard, the king of spies, against whom he had matched himself. He could not mistake, despite the darkness, his figure, his walk and the swing of his powerful shoulders.

His impulse was to cry for help, to shout that the spy was here, but at the first sound of his voice Shepard would at once dart into the shrubbery, and escape through the alleys of Richmond. No, his old feeling that it was a duel between Shepard and himself was right, and so they must fight it out.

Shepard walked swiftly toward the narrower and more obscure streets, and Harry followed at equal speed. The night grew darker and the rain, instead of coming in gusts, now fell steadily. Twice Shepard stopped and looked back. But on each occasion Harry flattened himself against a plank fence and he did not believe the spy had seen him.

Then Shepard went faster and his pursuer had difficulty in keeping him in view. He went through an alley, turned into a street, and Harry ran in order not to lose sight of him.

The alley came into the street at a right angle, and, when Harry turned the corner, a heavy, dark figure thrust itself into his path.

"Shepard!" he cried.

"Yes!" said the man, "and I hate to do this, but I must."

His heavy fist shot out and caught his pursuer on the jaw. Harry saw stars in constellations, then floated away into blackness, and, when he came out of it, found himself lying on a bed in a small room. His jaw was bandaged and very sore, but otherwise he felt all right. A candle was burning on a table near him and an unshuttered window on the other side of the room told him that it was still night and raining.

Harry looked leisurely about the room, into which he had been wafted on the magic carpet of the Arabian genii, so far as he knew. It was small and without splendor and he knew at once from the character of its belongings that it was a woman's room.

He sat up. His head throbbed, but touching it cautiously he knew that he had sustained no serious injury. But he felt chagrin, and a lot of it. Shepard had known that he was following him and had laid a trap, into which he had walked without hesitation. The man, however, had spared his life, although he could have killed him as easily as he had stunned him. Then he laughed bitterly at himself. A duel between them, he had called it! Shepard wouldn't regard it as much of a duel.
