The man at the door turned in a flash at the sound.

“Put ’em up!” he said sharply.

“Don’t shoot.” Leon’s voice was almost conversational in its calmness. “The house is surrounded by police.”

With an oath the man darted out of the door, and at that instant came the sound of the first shot, followed by desultory firing from the direction of the road. The second guard had been the first to go. Leon ran to the door, slammed it tight and switched on the lights as the two men came from the study. Under the arm of one was a thick pad of square brown sheets. He dropped his load and put up his hands at the sight of the gun; but his companion was made of harder material, and, with a yell, he leapt at the man who stood between him and freedom. Leon twisted aside, advanced his shoulder to meet the furious drive of the man’s fist; then, dropping his pistol, he stooped swiftly and tackled him below the knees. The man swayed, sought to recover his balance and fell with a crash on the stone floor. All the time his companion stood dazed and staring, his hands waving in the air.

There was a knock at the outer door. Without turning his back upon his prisoners, Leon reached for the bar and pulled it up. Manfred came in.

“The gentleman who shouted ‘Cuccini’ scared them. I think they’ve got away. There were two cars parked on the road.”

His eyes fell upon the brown sheets scattered on the floor and he nodded.

“I think you have all you want, Leon,” he said.

The detectives came crowding in at that moment and secured their prisoners whilst Leon Gonsalez and his friend went out on to the lawn to search for Gurther.

The man lay as he had fallen, on his face, and as Leon flashed his lamp upon the figure, he saw that the snake had struck behind the ear.
