They sprang apart. Ruff felt his nerves stiffen—felt himself constrained to hold even his breath as he widened a little the crack in the curtains. This was no stealthy entrance. The door had been flung open. Von Hern, his dress in wild disorder, pale as a ghost, and with a great bloodstain upon his cheek, stood confronting them.

“When you have done with your love-making,” he called out, “I’ll trouble you to restore my property!”

The electric light gleamed upon a small revolver which flashed out toward the young American. Paul Jermyn never hesitated for a moment. He seized the chair by his side and flung it at Von Hern. There was a shot, the crash of the falling chair, a cry from Jermyn, who never hesitated, however, in his rush. The two men closed. A second shot went harmlessly to the ceiling. The little lady stole away—stole softly across the room toward the table. She opened the drawer. Suddenly the blood in her veins was frozen into fear. From nowhere, it seemed to her, came a hand which held her wrists like iron!

“Madam,” Peter Ruff whispered from behind the curtain, “I am sorry to deprive you of it, but this is stolen property.”

Her screams rang through the room. Even the two men released one another.

“It is gone! It is gone!” she cried. “Some one was hiding in the room! Quick!”

She sprang into the hall. The two men followed her. The front door was slammed. They heard flying footsteps outside. Von Hern was out first, clearing the little flight of steps in one bound. Across the road he saw a flying figure. A level stream of fire poured from his hand—twice, three times. But Peter Ruff never faltered. Round the corner he tore. The man had kept his word—the brougham was already moving slowly.

“Jump in, sir,” the man cried. “Throw yourself in. Never mind about the door.”

They heard the shouts behind. Peter Ruff did as he was bid, and sat upon the floor, raising himself gradually to the seat when they had turned another corner. Then he put his head out of the window.

“Back to the Duchess of Montford’s!” he ordered.
