"Well," he said, "how's things?"

Spargo, half-breathless, dropped into his desk-chair.

"You didn't come here to tell me that," he said.

Rathbury laughed.

"No," he said, throwing the newspaper aside, "I didn't. I came to tell you my latest. You're at full liberty to stick it into your paper tonight: it may just as well be known."

"Well?" said Spargo.

Rathbury took his cigar out of his lips and yawned.

"Aylmore's identified," he said lazily.

Spargo sat up, sharply.

"Identified!"

"Identified, my son. Beyond doubt."

"But as whom--as what?" exclaimed Spargo.

Rathbury laughed.

"He's an old lag--an ex-convict. Served his time partly at Dartmoor.

That, of course, is where he met Maitland or Marbury. D'ye see? Clear as noontide now, Spargo."

Spargo sat drumming his fingers on the desk before him. His eyes were fixed on a map of London that hung on the opposite wall; his ears heard the throbbing of the printing-machines far below. But what he really saw was the faces of the two girls; what he really heard was the voices of two girls ...

"Clear as noontide--as noontide," repeated Rathbury with great cheerfulness.

Spargo came back to the earth of plain and brutal fact.

"What's clear as noontide?" he asked sharply.

"What? Why, the whole thing! Motive--everything," answered Rathbury.

"Don't you see, Maitland and Aylmore (his real name is Ainsworth, by the by) meet at Dartmoor, probably, or, rather, certainly, just before Aylmore's release. Aylmore goes abroad, makes money, in time comes back, starts new career, gets into Parliament, becomes big man. In time, Maitland, who, after his time, has also gone abroad, also comes back. The two meet. Maitland probably tries to blackmail Aylmore or threatens to let folk know that the flourishing Mr. Aylmore, M.P., is an ex-convict. Result--Aylmore lures him to the Temple and quiets him.

Pooh!--the whole thing's clear as noontide, as I say. As--noontide!"

Spargo drummed his fingers again.

"How?" he asked quietly. "How came Aylmore to be identified?"

"My work," said Rathbury proudly. "My work, my son. You see, I thought a lot. And especially after we'd found out that Marbury was Maitland."

"You mean after I'd found out," remarked Spargo.

Rathbury waved his cigar.

"Well, well, it's all the same," he said. "You help me, and I help you, eh? Well, as I say, I thought a considerable lot. I thought--now, where did Maitland, or Marbury, know or meet Aylmore twenty or twenty-two years ago? Not in London, because we knew Maitland never was in London--at any rate, before his trial, and we haven't the least proof that he was in London after. And why won't Aylmore tell? Clearly because it must have been in some undesirable place. And then, all of a sudden, it flashed on me in a moment of--what do you writing fellows call those moments, Spargo?"

"Inspiration, I should think," said Spargo. "Direct inspiration."

"That's it. In a moment of direct inspiration, it flashed on me--why, twenty years ago, Maitland was in Dartmoor--they must have met there!

And so, we got some old warders who'd been there at that time to come to town, and we gave 'em opportunities to see Aylmore and to study him.

Of course, he's twenty years older, and he's grown a beard, but they began to recall him, and then one man remembered that if he was the man they thought he'd a certain birth-mark. And--he has!"

"Does Aylmore know that he's been identified?" asked Spargo.

Rathbury pitched his cigar into the fireplace and laughed.

"Know!" he said scornfully. "Know? He's admitted it. What was the use of standing out against proof like that. He admitted it tonight in my presence. Oh, he knows all right!"

"And what did he say?"

Rathbury laughed contemptuously.

"Say? Oh, not much. Pretty much what he said about this affair--that when he was convicted the time before he was an innocent man. He's certainly a good hand at playing the innocent game."

"And of what was he convicted?"

"Oh, of course, we know all about it--now. As soon as we found out who he really was, we had all the particulars turned up. Aylmore, or Ainsworth (Stephen Ainsworth his name really is) was a man who ran a sort of what they call a Mutual Benefit Society in a town right away up in the North--Cloudhampton--some thirty years ago. He was nominally secretary, but it was really his own affair. It was patronized by the working cla.s.ses--Cloudhampton's a purely artisan population--and they stuck a lot of their bra.s.s, as they call it, in it. Then suddenly it came to smash, and there was nothing. He--Ainsworth, or Aylmore-- pleaded that he was robbed and duped by another man, but the court didn't believe him, and he got seven years. Plain story you see, Spargo, when it all comes out, eh?"

"All stories are quite plain--when they come out," observed Spargo.

"And he kept silence now, I suppose, because he didn't want his daughters to know about his past?"

"Just so," agreed Rathbury. "And I don't know that I blame him. He thought, of course, that he'd go scot-free over this Marbury affair.

But he made his mistake in the initial stages, my boy--oh, yes!"

Spargo got up from his desk and walked around his room for a few minutes, Rathbury meanwhile finding and lighting another cigar. At last Spargo came back and clapped a hand on the detective's shoulder.

"Look here, Rathbury!" he said. "It's very evident that you're now going on the lines that Aylmore did murder Marbury. Eh?"

Rathbury looked up. His face showed astonishment.

"After evidence like that!" he exclaimed. "Why, of course. There's the motive, my son, the motive!"

Spargo laughed.

"Rathbury!" he said. "Aylmore no more murdered Marbury than you did!"

The detective got up and put on his hat.

"Oh!" he said. "Perhaps you know who did, then?"

"I shall know in a few days," answered Spargo.

Rathbury stared wonderingly at him. Then he suddenly walked to the door. "Good-night!" he said gruffly.
