"Anyway, what I'm guessin' is that maybe I'd better examine my take-off before I do too much leapin'. And my take-off is that the elevator-man says he saw you in the Heberworth Building. That ain't a hangin' matter, exactly, I tells myself. Suppose I get a little more.

"What sort of a lady is this Florine Ladue, I asks myself. An actress, or somebody that wants to be an actress; well, where would she be livin'? Somewhere in the Tenderloin, most likely. So, last evenin', I get busy. And I find at the Napoli that Miss Florine Ladue registered there last Monday and beat it away after breakfast Wednesday mornin'. And that's proof to me that Florine Ladue didn't do the killing.

"Now, I'm pretty sure that you're Florine Ladue all right. Madame Napoli described you pretty thoroughly. Even told me that you was readin' a paper, at breakfast, what paper it was, how you got a telegram supposed to be from your mother that called you away. Now, I figure it out to myself: If Miss Ladue's mother wired her, and the wire made Miss Ladue pack her stuff and beat it, why didn't she go home? Because the wire's a fake, most likely. Then why, the next question is, did Miss Ladue put over that fake? The answer's easy. Because she'd just read in the mornin' paper about Beiner's murder. She's read about a young woman climbin' down the fire-escape, thinks she'll be pinched as that young woman, and—beats it. Pretty good?"

Clancy nodded. She looked at the man with narrowed eyes.

"Still," she said, "I don't understand why you're sure that Miss Ladue didn't kill him."

Spofford's smile was complacent.

"I'll tell you why, Miss Deane. This Ladue lady is no fool. The way she beat it from the Napoli proves that she was clever. But a clever woman, if she'd murdered Beiner, would have beat it Tuesday afternoon! Miss Deane, if you'd left the Napoli on Tuesday, I'd stake my life that you killed Beiner. No woman, leastwise a young girl like you, would have had the nerve to sit tight like you did on Tuesday night. I may be all wrong, but you gotta show me if I am," he went on emphatically. "Suppose you had killed Beiner, but didn't know that any one had seen you on the fire-escape! Even then, you'd have moved away from the Napoli. I tell you I been twenty-seven years on the force. I know what regular criminals do, and amachures, too. And even if you'd killed Beiner, I'd put you in the amachure class, Miss Deane."

"Let's go a little farther," suggested Clancy. "Why did I announce myself to Mr. Vandervent as Florine Ladue and then deny it?"

"You was scared," said Spofford. "Then, after you'd sent in that name, you read a paper sayin' Fanchon DeLisle was dead. You knew no one could identify you as Florine. You see, I picked up the paper on the bench where you'd been sittin'."

"Mr. Spofford," said Clancy slowly, "I think that you are a very able detective."
