the moment he is himself a--what you call it--suspect? In this case
it is so simple, if only the honest men will make no trouble. They will
say to you--'Search me.' You do so, and at last one comes who says, 'You
insult me.' That one is of course the thief, eh, Monsieur, do you not
agree with me?" He turned towards Mr. Barnes, addressing this last
remark to him. The detective looked at him a moment steadily, as was his
wont when he meant to remember a face. The Frenchman returned the gaze
undisturbed.

"I said almost the same thing to the conductor before you came in," said
Mr. Barnes.

"Exactly so. Now then with your permission I will disrobe. Look, if you
please, most carefully. My honor is at stake. The more carefully you
examine, the less suspicion can attach to me hereafter."

The conductor made a thorough search, emptying every pocket and taking
every precaution. He did not expect to find anything, but it was
essential that extreme care should be observed. Nothing was found, and
the man resumed his clothing.

"Now, if you please, I have with me but two small satchels. If the
porter will bring them I will unlock them for you. I have no trunk, as I
only went to Boston for a day's trip."

The satchels were brought, examined, and nothing found.

"Now, gentlemen, I suppose I am free, as we are at my station. I shall

ever want him, I could find him again. Here is his name--Alphonse
Thauret--card genuine too, of French make and style of type. We can
dismiss him now and turn our attention to the other passengers. Do you
suppose I could have an interview with the woman?"

"You shall have it if you wish. We will not consult her wishes in the
matter. The affair is too serious."

"Very well then send her in here and let me have a few words with her
alone. Don't tell her that I am a detective. Leave that to me."

A few minutes later a tall woman apparently about forty-five years of
age entered. She was not handsome yet had a pleasing face. As she seated
herself she looked keenly at Mr. Barnes in a stealthy manner which
