rn you, pray, sir?" I asked angrily.

"Ah! calm yourself, m'sieur," he said suddenly, dropping into French;
"I am here as your friend."

"I hardly believe that," I replied incredulously. "My friend cannot be
the accomplice of my enemies. You are acquainted with Reckitt and with
Pennington--the men implicated in the recent theft of the diamonds of
the Archduchess Marie Louise!"

He started and looked at me quickly.

"What do you know of that?" he inquired, with rather undue eagerness.

"I know more concerning you than you think," was my firm reply. "And I
give you an alternative, Monsieur Guertin. Either you will reveal to
me the whole truth concerning those men Reckitt and Forbes and my
wife's connection with them, or I shall telephone to the police, and
have you arrested as a member of the gang."

"My dear monsieur," he replied, with a good-humoured smile, "I can't
tell you facts of which I possess no knowledge. I am here to make

"To mislead me further!" I cried angrily. "You and your friends may be
extremely clever--you have succeeded in enticing my wife away from her

"Put that thing away," he urged. "Be reasonable. What would you profit
by arresting me?"

"You shall either speak--tell me the truth, or I will hand you over to
the police. I have only to touch this bell"--and I raised my hand to
the electric button beside the fireplace--"and a telephone message
will call a constable."

"And you really would give me in charge--eh?" laughed my visitor.

"I certainly intend doing so," I answered angrily.

"Well, before this is done, let us speak frankly for a few moments,"
suggested the Frenchman. "You tell me that you nearly lost your life
in some house in Bayswater. Where was that?"

"In Porchester Terrace. What is the use of affecting ignorance?"

"I do not affect ignorance," he said, and I saw that a change had
completely overspread his countenance. "I only wish to know the extent
of your knowledge of Reckitt and Forbes."

"I have but little knowledge of your friends, I'm pleased to say," was
my quick rejoinder. "Let
