May I not hope so ?" "Perhaps," she murmured.
"Only perhaps ?" Looking up, she read my face with a quick, deep glance.

"Yes," she said, "I think I may tell you--some time": and so our conversation ended, for she gave me no chance to say anything more.
That night I don't think even Dr.Pillsbury could have put me to sleep, till toward morning at least.

Mysteries had been my accustomed food for days now, but none had before confronted me at once so mysterious and so fascinating as this, the solution of which Edith Leete had forbidden me even to seek.

It was a double mystery.

How, in the first place, was it conceivable that she should know any secret about me, a stranger from a strange age?
In the second place, even if she should know such a secret, how account for the agitating effect which the knowledge of it seemed to have upon her?
There are puzzles so difficult that one cannot even get so far as a conjecture as to the solution, and this seemed one of them.
