How do you know she has gone?"

"At least, she is no longer with us out there. Have you arrested her--or
what?"

"No, she is still at large, but we have our eye upon her. She has gone
to her hotel--the Madagascar, off the Grands Boulevards."

"Then it is there that I shall look for the maid. No doubt she preceded
her mistress to the hotel, or she will join her there very shortly."

"You would not make yourself known, of course? They might give you the
slip. You have no authority to detain them, not in France."

"I should take my precautions, and I can always appeal to the police."

"Exactly. That would be your proper course. But you might lose valuable
time, a great opportunity, and we wish to guard against that, so we
shall associate one of our own people with you in your proceedings."

Put yourself in communication with Galipaud, who is there on duty."

"Would it not be sufficient if I made myself known to M. Galipaud?"
suggested the Italian. "I have seen him here, I should recognize him--"

"That is not so certain; he may have changed his appearance. Besides,
he does not know the latest developments, and might not be very
cordial."

"You might write me a few lines to take to him."

"I think not. We prefer to send Block," replied the Chief, briefly and
decidedly. He did not like this pertinacity, and looked at his
colleagues as though he sought their concurrence in altering the
arrangements for the Italian's mission. It might be wiser to detain him
still.

"It was only to save trouble that I made the suggestion," hastily put in
Ripaldi. "Naturally I am in your hands. And if I do not meet with the
maid at the hotel, I may have to look further, i
