esents in connection with the cotillon promoted by the Marquis.
At two o'clock the following morning the Marquis was entertaining a
select party in the smoking-room. The ladies had all vanished by this
time. The Marquis was speaking of his adventures. He really had quite a
talent in that direction. Naturally, a man of his wealth was certain to
be the mark for swindlers. Merrick listened with an approving smile. He
knew that most of these stories were true, for they had all been
recorded from time to time at Scotland Yard.
"You would have made an excellent detective, Marquis," he said. "You
have made it quite clear where the police blundered over that Glasgow
tragedy. I suppose you read all about the Grand Coast Railway murder."
The Marquis started ever so slightly. There was a questioning look in

"You want to speak to me, Colonel?" he said.
"Very much indeed. Now, you are an exceedingly clever man, Marquis, and
you may be able to help me. It happens that I am deeply interested in
the Grand Coast Express murder; in fact, I have devoted the last two
months to its solution."
"With no success whatever, my dear Colonel?" the Marquis murmured.
"On the contrary, my dear Marquis, with absolute satisfaction. I am
quite sure that you will be interested in my story."
The Marquis raised his cigarette graciously.
"You are very good to give me your confidence," he said. "Pray proceed."
"Thank you. I will not bore you with any preliminary details, for they
