“Posy, you’re a good girl,” Lora said, feeling, I was sure, that somebody ought to give the girl the applause she had earned. “But you’re going to keep those things secret for us, aren’t you?”

“Yes’m, I’m going to do just what you and Mr. Moore tell me. For I’ve made up my mind. I’ve found myself and I’m going to make detective work my vocation. I think I have a decided talent for it, and I am sure——”

“Well, Posy,” Keeley said, suddenly waking up, “if you want to be a detective one of the first things to learn is to keep your mouth shut. Can you do that?”

“Yes, sir. I’ve just promised Mrs. Moore not to say a word until you say I may.”

“That’s a good girl. Now if that finishes your report, I’ll excuse you for to-day. I have to act upon your information, you know. You feel sure, don’t you, that these episodes happened just as you’ve narrated them?”

“Yes, I do. I know those girls, and what they say they saw, they saw. Daisy said she thought Alma was a little lacking, but the others didn’t say that, they only thought she had a fierce temper that broke out suddenly sometimes.”

“Either of those things may be true, but don’t think about it. Run off now, and play with your sheik. And forget all about this case unless you get some further knowledge that is both true and important. But, remember, not a word of it to any one—not any one at all!”

“See my finger wet, see my finger dry, see my finger cut my throat if I tell a lie,” said the girl, in a singsong tone, and with accompanying dramatic gestures of fearful histrionic fervour.

Then she ran away, and we sat and looked at one another.

“The problem seems to be solved,” I said.
