"You mean Luke Walton?"

"Yes, the newsboy, whom you have so imprudently trusted."

"What are your reasons for thinking he is a thief?" asked the old lady calmly.

"He is often alone in the room where the work table stands, is he not?"

"Yes; he waits for me there."

"What could be easier than for him to open the drawer and abstract the pocketbook?"

"It would be possible, but he would have to unlock the drawer."

"Probably he took an impression of the lock some day, and had a key made."

"You are giving him credit for an unusual amount of cunning."
