“Of course, and I’m ready to tell all I know. Go on and ask questions.”

“Well, then, what do you surmise has become of that five hundred dollars and that ruby stickpin? Doesn’t their disappearance rather argue against suicide?”

“No, Doctor Waring had no safe. There has been little or no robbery in Corinth, and Doctor Waring rarely kept much money about.”

“Five hundred dollars is quite a sum.”
