"Chapman!"

"What a funny idea, to call out! Isn't my company enough for you?"

"Chapman!" Mr. Kesselbach cried again. "Chapman! Edwards!"

"Chapman! Edwards!" echoed the stranger, in his turn. "What are you doing? You're wanted!"

"Sir, I ask you, I order you to let me pass."

"But, my dear sir, who's preventing you?"

He politely made way. Mr. Kesselbach walked to the door, opened it and gave a sudden jump backward. Behind the door stood another man, pistol in hand. Kesselbach stammered:

"Edwards . . . Chap . . ."

He did not finish. In a corner of the lobby he saw his secretary and his servant lying side by side on the floor, gagged and bound.

Mr. Kesselbach, notwithstanding his nervous and excitable nature, was not devoid of physical courage; and the sense of a definite danger, instead of depressing him, restored all his elasticity and vigor. Pretending dismay and stupefaction, he moved slowly back to the chimneypiece and leant against the wall. His hand felt for the electric bell. He found it and pressed the button without removing his finger.
