"Go on!" snapped Smith. "I know her."

"He saw her a good many times—and she came here once or twice. She made out that she and Singapore Charlie were prepared to give away the boss of the Yellow gang—"

"For a price, of course?"

"I suppose so," said Burke; "but I don't know. I only know that I warned him."

"H'm!" muttered Smith. "And now, what took place to-night?"

"He had an appointment here with the girl," began Burke.

"I know all that," interrupted Smith. "I merely want to know what took place after the telephone call."

"Well, he told me to wait up, and I was dozing in the next room to the study—the dining-room—when the 'phone bell aroused me. I heard the lieutenant—Mr. Slattin—coming out, and I ran out too, but only in time to see him taking his hat from the rack—"

"But he wears no hat!"

"He never got it off the peg! Just as he reached up to take it, he gave a most frightful scream, and turned around like lightning as though some one had attacked him from behind!"
