"Yes," replied Aurelia, nodding once or twice. "I am sure she knows something. I went into her room before luncheon, and she was sitting 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 know,"—with a shake of the curls—"though people may think me only a silly little thing, yet I do notice things, Colonel Middleton. Aunt 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," she replied. "Ralph is remaining with him."

"He is better, then, I hope?"

"He is in a very critical state, and is likely to remain in it. His illness was quite serious enough, without having it increased by one of his own household."

"Ah, I was afraid that had been the case," returned Charles. "I knew you had been doctoring him when he was out of sorts yesterday. But you must not reproach yourself, Aunt Mary. We are none of us infallible. No doubt you acted for the best at the time, and I dare say what you gave him may not do him any permanent injury."

"If that is intended to be amusing," said Lady Mary, her teacup trembling in her hand, "I can only say that, in my opinion, wilfully misunderstanding a simple statement is a very cheap form of wit."

"I am so glad to hear you say so," said Charles, rising, "as it was at your expense." With which Parthian shot he withdrew.

I endeavored in vain to waylay Evelyn after tea, but she slipped away almost before it was over, and did not appear again till dinner-time. In the mean while my brain, fertile in expedients on most occasions, could devise no means by which I could speak to her alone, and without Charles's knowledge. I felt I must trust to chance.
