She shook her head, thoughtfully knuckling her underlip.

"How can I communicate with you in event of necessity after we get to New
York?" she asked.

"I shall stop for a week or two at the Hotel Knickerbocker."

"If anything should happen"--with a swift glance of anxiety toward the
motionless figure in the berth--"if anything should prevent my calling for
it within a week after our arrival, you will be good enough to deliver it
to--" She caught herself up quickly, the unuttered words trembling on her
lip. "I will write down the address of the person to whom you will deliver
it, and slip it underneath the door between our rooms--first making
certain you are there to receive it--if I do not ask you to return
the--thing--before we land."

"That shall be as you will."

"When you have memorized the address you will destroy it?"

"Depend on that."

"I think that is all. Thank you, Monsieur Duchemin--and good-night."

She extended her hand. He saluted it punctiliously with fingertips and
lips.

"If you will put out the light, mademoiselle, it may aid me to get away
unseen."
