"You ought to know that by this time"—aggrieved.

Haggerty tossed the bunch of keys on the table.

"Ha! Good specimens, these," Forbes declared, handling them. "Here's a window-opener."

"Good boy!" said Haggerty, as a teacher would have commended a bright pupil.

"And a door-chain lifter. Nothing lacking. Did he hit you with these?"

"Ye-up."

"What are these regular keys for?"

"One o' them unlocks a door." Haggerty smoked luxuriously.

Forbes eyed the ordinary keys with more interest than the burglarious ones. Haggerty was presently astonished to see the artist produce his own key-ring.
