“Indirectly. She gave some information to our express messenger who in turn gave it to me. I might add that the interest of our messenger ceased when I took up this case.”

“Very well” replied Donna, and proceeded to tell him with infinite detail, everything she knew concerning Bob McGraw, excepting the fact that he was her husband. In five minutes she had tightened the web of circumstantial evidence around him, and then unloosened it, and at the finish of her recital the detective had no questions to ask. He held out his hand and shook hers warmly.

“I think you have solved this case for me, Miss Corblay. However, there is one matter that will be hard to overcome, and that is the identification of McGraw by the passenger, Carey.”

“Who?”

“A passenger. His name is T. Morgan Carey, of Los Angeles. He is rather prominent in business circles—a pretty sane, careful man, and his testimony would have considerable evidence with a jury.”

“Find out from the messenger if Carey identified Bob—I mean Mr. McGraw (the detective smiled slightly) before the messenger gave chase to the hold-up man, or after he returned with the hat. If the latter, I can explode his testimony. I happen to know that Mr. Carey is a business rival of Mr. McGraw's and very unfriendly to him. It would be to Carey's great financial advantage to see Bob (again the detective smiled) in jail. Then ask your agent at Keeler to make inquiry and learn if a tall young man with auburn hair didn't ride into town the day following the hold-up, mounted on a roan horse. If he sold the horse, saddle and spurs, purchased two burros and outfitted in Keeler for a prospecting trip, that man was Mr. Robert McGraw and he didn't arrive bareheaded. I think you'll discover that you're following a false lead.”

The detective could guess a thing or two; otherwise he would not have been a detective. He guessed something of Donna's more than friendly interest in the man he was after; an interest which he felt to be greater than a mere feeling of gratitude for what McGraw had saved her from, and his sympathies wore with her. She had been “open and above board with him” and he appreciated the embarrassment that might attend should the matter be given publicity.

“Whatever I discover will not be made public, Miss Corblay. Thank you.”

He lifted his hat and walked out, while Donna, selecting one of the late magazines from the news-stand, sat down and read for the rest of the afternoon.

Eight days passed before the detective appeared again at the counter.
