“Just working out a little idea, that’s all.”

IN WHICH ASHTON-KIRK HEARS MATTERS OF INTEREST

THE special detective smiled and nodded.

“Just a moment,” said he; “there are a few little indications which I want to make sure of, then I’ll talk to you.” Swiftly he worked with the glass and a small ivory rule; then pocketing these he resumed the blue glasses and arose to his feet. “I gather from your words and your expression of face that you’re a trifle surprised!”
