"Why do you wish to know?"

Beatrice evaded this question dexterously, not thinking it wise to admit Mrs. Lilly into her confidence too largely. "Oh! Mrs. Snow talked a lot about it at the inquest."

"I heard about that, my dear. Strange that your stepfather should have been murdered by a man with a black patch over his left eye!"

"You agree with Mrs. Snow, then?"

"That the same man committed the other murder?" queried Mrs. Lilly musingly. "I can hardly say that. Certainly a black patch, that could have been worn over an eye, was found on the grass under Colonel Hall's window the morning after his murder, but----"

"The man was not seen, then?" interrupted Beatrice.

"No. Only from the presence of the black patch, the detective who had charge of the case thought it had been worn for the purpose of disguise. There was a great stir about the matter, as Colonel Hall was well known as a Government official. He came from some West Indian island, I believe, where he was Administrator or something," ended Mrs. Lilly vaguely.

"Well, then, tell me all from the beginning. Mrs. Snow has very little to go on, if that is all about the black patch. I saw Mr. Alpenny's murderer wearing it, you know; but neither Mrs. Snow nor any one else saw Colonel Hall's assassin with it on."

Mrs. Lilly nodded. "I heard of your experience. My dear, you should not run about the woods at night: it isn't ladylike. I wonder you didn't faint with horror when you saw the man!"

"I should have, had I known of this theory about Colonel Hall having been killed by such a man. As it was, I felt too worn-out to be startled by anything. Where ignorance is bliss. Go on, Mrs. Lilly; tell me all Mrs. Snow does not know."
