She held up a warning finger.

"That is not in the compact. You are not to be inquisitive. Ask me no
questions, please, but wait on events. For the present you must be
satisfied so, and there is nothing more to be said."

"I shall see you again, I trust," I pleaded, as she rose to leave me.

"If you wish, by all means. Why should we not dine together in the
dining-car by and by?" she proposed with charming frankness, in the
lighter mood that sat so well upon her. "The waiters will be there to
play propriety, and no Mrs. Grundy within miles."

"Or your maid might be chaperon at an adjoining table."

"Philpotts? Impossible! She cannot leave--she must remain on duty; one
of us must be in charge always. Who knows what might happen when our
backs were turned? We might lose it--it might be abstracted. Horrible
thought after all it has cost us."

"'It' has evidently an extraordinary value in your eyes. If only I
might be allowed to--" know more, I would have said, but she chose to
put other words into my mouth.

"To join us in the watching? Take your turn of 'sentry go'--isn't that
your military term? Become one of us, belong to a gang of thieves,
liable like the rest of us to the law? Ah, that would be trying you
too far. I see your face fall."
