“I do not know,” Mr. Sabin answered. “You will see that the two anonymous communications which I have received since arriving in New York yesterday are written in the same manner.”

Mr. Sabin handed him the other two letters, which Mr. Skinner carefully perused.

“I guess you’d better tell me who you are,” he suggested.

“I am the husband of the Duchess of Souspennier,” Mr. Sabin answered.

“The Duchess send any word home at all?” Mr. Skinner asked.

Mr. Sabin produced a worn telegraph form. It was handed in at Fifth Avenue, New York, at six o’clock on Friday. It contained the single word ‘Good-bye.’

“H’m,” Mr. Skinner remarked. “We’ll find all you want to know by to-morrow sure.”

“What do you make of the two letters which I received?” Mr. Sabin asked.

“Bunkum!” Mr. Skinner replied confidently.

Mr. Sabin nodded his head.
