Instantly Marsh slipped down in his chair, so that his head came below its back, while Morgan's hand shot out and snapped off the electric lamp on the table, throwing the room into darkness. Aside from the slight cracking of the window glass, and the dull crash as the missile struck the plastered wall, there had been no other sound.

Morgan left his chair and felt his way through the darkened room. Opening the hall door he cautiously peered out. Tierney, with his hands in his trouser pockets, was leaning with his back against the wall. He glanced up quickly as the door opened.

"Everything all right, Tierney?" inquired Morgan.

"Sure thing."

"Haven't seen or heard anybody?"

"Nope."

Morgan closed the door and moved back into the room.

"'Dead men tell no tales'," said Marsh, lightly.

"Was it that, or just a warning?" questioned Morgan.

"People do not go to all that trouble just to deliver a warning, Morgan. They wanted to get me."
