Philo Gubb sat on the ladder and contemplated the five-dollar bill until he heard Fogarty returning.

“Hist!” Fogarty said. “I did not see him, mind ye!”

Fogarty slipped out of the back door and was gone, and Philo Gubb, after a thoughtful moment, decided that the five-dollar bill was rightfully his, and slipped it into his pocket. To earn it, however, he must get to work on the case. He raised the pasted strip of paper, but before he could place the loose end on the ceiling, some one tapped at the kitchen door.

“Come in!” he called, and the door opened.

“Slippery” Williams glided into the room. His crafty eyes sought Philo Gubb.

“’Lo, Gubby! Watcha doin’ up there? Where’s Miss Turner?” he asked.

“Miss Turner is out on business, I presume,” said the Correspondence School detective coldly, “and I am pursuing my professional duties in the deteckating line.”

“Yar, hey?” said Slippery. “Who you detectin’ for now?”

“Snooks Turner,” said Philo Gubb. “I’m solving a case for him.”
