"That," said Radnor contemptuously, "refers to two bonds which I bought last winter with some money I got from selling a mortgage. I preferred to have the investment in bonds because they are more readily negotiable. I left them at my broker's as collateral for another investment I was making. Last week I needed some ready money and wrote to them to sell. My statement can easily be substantiated; no reputable detective would ever base any such absurd charge on the contents of a letter he did not understand."

"Of course," said the detective, "we have tried to get at the matter from the other end; but Jacoby, Haight & Company refuse to discuss the affairs of their clients. I did not press the point as I did not want to stir up comment. However," he smiled, "I must confess, Mr. Gaylord, that I think your explanation a trifle fishy. Perhaps you will answer one question. Did you mail your letter to them in Kennisburg the night of the robbery with a special delivery stamp?"

"It happens that I did, but it was merely a coincidence and has nothing to do with the robbery."

"Will you be kind enough to explain why you drove to Kennisburg in the night and why you needed the money so suddenly?"

"No, I will not. That is a matter which concerns, me alone."

"Very well! As it happens I do not base my charge on the letter; I had already formed my opinion before I knew of its existence. Do you deny that you yourself have encouraged the belief in the ghost among the negroes? That on more than one occasion, you, or your accomplice, Cat-Eye Mose, have masqueraded as the ghost? That, while you were pretending to Colonel Gaylord to be as much puzzled by the matter as he, you were in truth at the bottom of the whole business?"

Radnor glanced uneasily at me and hesitated before replying.

"No," he said at length, "I don't deny that, but I do affirm that it has nothing to do with the robbery."

The detective laughed.

"You must excuse me, Mr. Gaylord, if I stick to the opinion that I have solved the puzzle."
