ign that Vance had been aroused.

At last he relaxed again. Reached through the broken pane and unlocked
the big window. Swung it open, ever so gently, and stepped inside,
fading swiftly into the thick blackness of the nearest corner.

Once Mark had interviewed a burglar as a feature assignment. He
remembered the man's words now.

"Gettin' in ain't the hard part," the second-story worker had explained.
"It's gettin' out that's tough. The first thing you gotta do on a job is
to line up an exit."

Now, as his eyes grew accustomed to the blackness, Mark searched for a

flashlight hit him square in the face like a physical blow. It blinded
him. Left him helpless.

"No doubt this is just a social call. Too bad that the police will call
it breaking and entering with larcenous intent!"

It was the oily, mocking voice of Adrian Vance, and it came from the
French window through which Mark had entered.

"Try to lie out of it!" Vance gloated. "Just try to explain that picture
in your hands!"

"I don't have to explain, Vance. You know why I'm here."

The wail of a siren sounded in the distance.

"Oh, of course I know." The other was laughing softly, greasily. "But
will the police understand, Carter? That siren you hear--it's coming
here, you know; I called the station before I came d
