t was not Charles after all.
Perhaps--

"I am afraid Evelyn is very unhappy," continued Aurelia. "Her room is
next to mine, and she walks up and down, and up and down, in the night.
I hear her when I am in bed. Last night I heard her so late, so late
that I had been to sleep and had waked up again. Do you know," and she
crept close up to me with wide, awe-struck eyes, "I am going away
to-morrow, and I don't like to say anything to any one but you; but I
think Evelyn knows something."

"Miss Derrick!" I said, beginning to suspect that she possibly knew a
good deal more than any of us, and then suddenly remembering that she
had been on the point of telling me something and had been interrupted.
I was getting quite confused. She certainly would not have wished to
confide in me if my new suspicion were correct. Considering there was a
mystery, it was curious how every one seemed to know something very
particular about it.

"Yes," replied Aurelia, nodding once or twice. "I am sure she knows

with her head down on the dressing-table, and when she looked up I saw
she had been crying. I don't know what to say about it to Ralph; but you

Alice in Dublin often says how quickly I notice things. And I thought,
as you were staying on, and seemed to be a friend, I would tell you this
before I went away, as you would know best what to do about it."

Aurelia had more insight into character than I had given her credit for.
She had hit upon the most likely person to follow out a clew, however
slight, in a case that seemed becoming more and more complicated. I
inwardly resolved that I would have it out with Miss Derrick that very
evening. Lady Mary now came in, and servants followed shortly afterwards
with lamps. The dreary twilight, with its dim whirlwinds of driving
snow, was shut out, the curtains were drawn, and tea made its
appearance. Evelyn presently returned, and Charles also, who civilly
wished Lady Mary good-morning, not having seen her till then. She handed
him his tea without a word in reply. It was evident that she, also, was
aware of the robbery, and it is hardly necessary to add that she
suspected Charles.

"How is my father?" he asked, taking no notice of the frigidity of her
manner.

"He is asleep at this moment,
