But this time it was the antiquarian who was surprised. He jerked back. Already his adversary was leaping for the cover of a heavy mahogany table. Vance snapped a shot at him. Tried again to place him with the light.

Mark's hand came down on a porcelain vase. He hurled it at Vance with all his might.

Vainly, his enemy tried to dodge. But too late. The vase thunk'd home against his left shoulder. The flashlight fell to the floor.

Like a thunderbolt, Elaine's fiance lunged forward. His left hand slashed down; pinioned the arm that held the Magnum. His right fist came up with express-train speed. Smashed home on the point of Vance's jaw. The antiquarian's body jerked spasmodically. Went limp. Sagged to the floor.

But now the sound of harsh voices and running feet came to Mark's ears.

Clutching the Jerbette painting in one hand, he ducked back out the window. Even in the gloom he could see black figures converging on the house. A sedan stood in the driveway, its spotlight sweeping the house.

"The police!"

Cold sweat stood out on Mark's forehead as he gasped the exclamation. But he did not hesitate. Keeping to the shadows, he headed for the still-open gate through which the car had come.

The iron fence loomed close. He ran along it in a half-crouch.

"Hey, you! Stick 'em up or we shoot!"
