Not that I think Roland Warren was the finest man in the world, or anything like that. Of course, I do believe he was interested in me, and that made me know him pretty well; but still he was an awfully nice boy, and I'm sure Hazel was very much in love with him. So even if she could have killed him, she wouldn't, would she?"

"I hope not; but you said she _couldn't_. What did you mean by that?"

"I mean that n.o.body can be in two places at one time. Although I did read a funny article in the Sunday magazine section of one of the big newspapers, last year, which said that--"

"If Miss Gresham had been with Mr. Warren last night at midnight--she would have been in two places at one time!"

"Why, yes--and that's not possible; so, of course, she--"

"What makes you think that, Miss Rogers!"

"Think what?"

"That Miss Gresham was not with Mr. Warren at midnight last night?"

"Why," answered Evelyn Rogers simply, "I _know_ she wasn't--that's all."

"You _know_?"

"Yes, indeed--beyond the what-you-call-'em of a doubt."

"How do you know that?"

"It's very simple," she explained casually. "She was with me all night."

Carroll gazed at the girl before him with new interest. Out of her chatter he had at last garnered one important fact. His mind, trained to seize upon the vital and instantly discard the inconsequential, clutched the bit of information, and turned it over. From the first Carroll had scouted the idea that the dead man's fiancee might have been responsible for his death; but still it was a line of investigation which demanded examination, and his pretty young visitor was making that road exceedingly simple. He injected all the warmth of his friendly, sunny nature in the smile which he bestowed upon her.

"You have helped me tremendously with that piece of information, Miss Rogers."

"I don't see how, particularly. No one with any sense--provided they knew Hazel, of course--could even imagine her killing any one, and least of all an adorable boy like Roland. She was so much in love with him!"

"Of course, I haven't the pleasure of Miss Gresham's acquaintance."

"Of course not. You'll have to meet her, though. She's a darling!

Naturally, she's all broken up this morning because her wedding date was all set. Now all her plans have gone smash, and she really was _terribly_ fond--"

"You say you spent the night with Miss Gresham?"

"Certainly, and--"

"Where?"

"At her house."

"And you are sure she was there all night?"

"Of course! We slept in the same bed--and that's certainly proof enough, isn't it?"

"I suppose so."

"You _suppose_? My goodness gracious! Don't you _know_?"

"Well--yes. If you're sure--"

"Why, my dear Mr. Carroll, we didn't even actually go to bed until a quarter before twelve. At ten o'clock we made some waffles downstairs--Hazel has just bought a perfectly _darling_ aluminum electric waffle-iron. It makes the most toothsome waffles--all crisp and everything. And you know when you use aluminum you don't need any grease, so that makes the waffles much nicer. I'm getting horribly domestic since Hazel became engaged, because she is learning--"

"And after you made the waffles?"

"Oh! After that we went up-stairs to her room, and put on our kimonos, and had a heart-to-heart talk. I can't tell you what we talked about, because sometimes--well, it was atrociously risque--as women will, you know, and--"

"At a quarter before twelve you were still sitting up talking, and you had your kimonos on?"

"Yes, and--oh, you just ought to see Hazel's new kimono--pink _crepe de chine_, trimmed with satin. She looks simply ravishing in it. I told Sis I wanted one like it, but--"

"And then you went to bed?"

"Yes, just about then."

"You are sure Miss Gresham didn't get up!"

"Oh, I'm positive she didn't! I didn't get to sleep until after one o'clock, anyway, and I would have known."

"You've given me some valuable information, Miss Rogers; and I'll see to it that the newspapers correct any impression they may have left that Miss Gresham might have been connected with the crime. Meanwhile"--he rose--"I'm a bit overdue down at headquarters; so if you'll excuse me--"

Evelyn Rogers rose and stood before him. Her pretty little face was eager.

"I've really helped you, Mr. Carroll?"

"Enormously."

"Well, I wonder--you know I'm just _fiendishly_ anxious to be helpful in the world--I wonder if you'd let me help you some more?"

"I'd be delighted."

"Would you _really_?"

"Really!"

"And I can come to you any time to talk things over?"

"Whenever you get ready."

She clapped her hands.

"That's simply _exquisite_! You know, Mr. Carroll, I'm just simply crazy about you! I always have been, but I'm more so now than ever--just _hopelessly_!"

"Thank you."

She made her way to the door. There she turned, and there was a peculiar light in her eyes.
