zi laughed outright, so infectiously, that
Douglas joined in.

"No, I'm not!" he admitted. "Now, if you're not, either, we're all in
the same boat."

But Zizi was not to be put off with foolery.

"Mr. Douglas," she said, seriously, "truly, I'm on an important errand,
and one involving grave consequences. You can help greatly by giving me
that man's address, and help not only the girl of whom I spoke, but help
the cause of right and justice, even, perhaps, in a matter of life and
death. Don't refuse----"

"But if I don't refuse, I must at least inquire. And, suppose I tell you
that Mr. Harrison does not want his address known?"

"I assumed that. But, suppose I tell you that it may help to clear up
one of the greatest mysteries of the day if you will just give me a hint
where I can find that man. And, even though he has forbidden you to
tell, I think I can assure you that he won't mind my knowing the secret,
and if he does mind I'll persuade him to exonerate you."

Zizi had meant to take quite a different tack,--use hints of legal
authority or suggest his duty to humanity, but intuition told her that
this man was best persuaded by coaxing,--and Zizi could coax!

She succeeded only partly. After she convinced Douglas of the wisdom of
such a course he told her that John Harrison had been at the Hotel
Consul in Brooklyn, but had left there, and had left no further address.

Moreover, he declared he had no knowledge whatever of the whereabouts of
John Harrison at the present time.

"No!" and Zizi flashed a quizzical smile, "because he has changed his
name! I know that from your emphatic declaration! But I'll find him.
Good-by."

Zizi betook herself forthwith to the Hotel Consul.

A polite clerk informed her that Mr. Harrison had checked out, leaving
no address.

Determinedly she interviewed the cab drivers ranked in front of the
hotel, and by a lucky chance found the one who had driven Mr. Harrison
away. A proper bribe brought the knowledge that he had been driven to
the Wilfer, a much smaller hotel nearby.

To the Hotel Wilfer Zizi went, and learned there was no John Harrison
there, but a very few inquiries proved to her astute intellect that the
Louis Bartram, who was the only guest registered at that time on that
afternoon, was in all probability the man she sought. At any rate there
was no harm in trying.

She asked for an interview, and was connected with Mr. Bartram's rooms
by telephone.

"I want to
