There was a photograph of the man who had been identified with the arch conspirators of two years before, Martin. Only, now he had changed his name and appeared in a new role.

It was Marcus Del Mar!

. . . . . . .

Already, in the library of his bungalow, Del Mar had summoned one of his trusted men and was talking to him, when Henry, the valet, reentered after his trip to see us.

"They're coming as soon as they can," he reported.

Del Mar smiled a cynical smile. "Good," he exclaimed triumphantly, then, looking about at the electric fixtures, added to the man, "Let us see where to install the thing."

He walked over to the door and put his hand on the knob, then pointed back at the fixtures.

"That's the idea," he cried. "You can run the line from the brackets to this door-knob and the mat. How's that?"

"Very clever," flattered the man, putting on a heavy pair of rubber gloves.

Taking a pair of pliers and other tools from a closet in the library, he began removing the electric fixture from the wall. As Del Mar directed, the man ran a wire from the fixture along the moulding, and down the side of a door, where he made a connection.
