The implied threat decided the man, and without further attempt at evasion he said:

"Well, I suppose there ain't any use my runnin' any risk for a man that's nothin' to me. It's this way: Morgan's an old-time crook—I suppose you know that?" Mr. Barnes nodded, although this was news to him. Allen continued: "He's been at it since he was a kid. Was in the reformatory, and learned more there about crooked work in a year than he would have picked up in ten outside. He's never done time, though, since he graduated from that institution. Learned enough, I guess, to keep out of sight of your crowd. Two years ago he moved into this neighborhood and since then I've seen him in here a good deal. He took up with Tommy White—a young fellow that would have lived straight only he was in bad company, and was railroaded with a gang for a job he really had no hand in. That settled him. When he came out of Sing Sing he wasn't likely to go for a straight job at a dollar a day, when he could lay around idle and pick up a good thing every now and then that would keep him going. I guess he and Morgan done a good many jobs together; anyway, they never was short of money. One thing was funny about those two—nobody ever seen them in the daytime. They used to say they was 'workin',' but that didn't go with the crowd that hangs out here. Neither Morgan nor White would work if they could help it. They was just like brothers, those two, till White took up with this girl Nellie. I think Morgan was jealous of his luck from the first, 'cause the girl is a peach. One of your real blondes, without no bleachin' stuff. She's got a skin like velvet, and hands and feet like a lady. White soon found out that his pal was sweet on the girl, and many a time they've rowed over her. Finally, about two weeks ago the two of them was in here, and they was drinkin' pretty hard and just ready for a scrap, when the girl comes in. Morgan goes up to her and puts his arm round her and kisses her plump. White was mad in a minute, but he turned on her instead of him and he says, says he: 'Nellie, I want you to hammer that duffer over the head for doin' that,' and he picks up a beer glass and hands it to her. Nellie she takes the glass, and she says: 'I've heard of a kiss for a blow,' she says, 'but a blow for a kiss is a new one on me. It ain't that way in the Bible, Tommy, so I guess if you want any hammerin' done, you'd better do it yourself. I'm thinkin' of joinin' the Salvation Army, you know.' This made Morgan and the crowd laugh, and White got fierce. He snatched the glass out of Nellie's hand and made for Morgan. But Morgan he ducks and lets White go by him, and he picks up a beer glass too; then when White came for him again he landed a terrible blow with the glass right back of White's ear. Tommy went down in a heap and lay on the ground quiverin'. The whole thing happened so quick nobody could interfere. Morgan got sober in a second, I tell you, and he was scared. Everybody crowded round, and the girl she was a wonder. You'd think bein' a woman she'd cry and make a fuss? Not a bit of it. She got some ice and put it on White's head, and threw water in his face, and she puts her ear down to his heart, and then she looks up after a bit, and she says, as cool as could be: 'Boys, he's only stunned. He'll come round all right. Some of you help get him home, and I'll look after him. He'll sleep off his liquor and he won't know what hurt him when he wakes in the mornin'.' Well, Morgan and the others they did what she said. They took White up and carted him over to his flat, and put him to bed. My! but he was limp, and his face was that blue it's been before me ever since."

"Did White get over that blow?"

"That's the point. Nellie and Morgan said he did; that he was a bit sore next day and had a headache. That was likely enough. But when you talked about murder a while ago, I admit I got scared, cause White's never been seen since that night."

"You are sure of that?"

"Dead sure. Nellie said he was gone out of town, and the boys swallowed the story. But when both Morgan and Nellie skipped it looked bad, and folks began to talk. As for me, I've been nervous for days. Why, when that body was picked out of the river I just couldn't keep away from the Morgue. I just had to have a peep at it. I was sure it would be White, and that Morgan had pitched him over. My, but wasn't I glad to see it was another man!"

Assuring Allen that his story would not be used in any way that would bring him into conflict with the authorities, Mr. Barnes left the saloon and went to his office, feeling that at last this problem had been solved. Evidently White had died of his wound, and when Morgan learned that the coffin of Mr. Quadrant was not to be opened before it was consigned to the crematory, he had conceived one of the most ingenious schemes ever devised for disposing of a murdered body. By placing White in the coffin and allowing his body to be incinerated, all traces of his crime would seem to have been obliterated. To accomplish this it was necessary to have the use of the undertaker's wagon, and this he had managed by drugging the watchman, as well as Mark Quadrant. The transfer made, he was still left with the other body, and his disposition of that was the most ingenious part of the plan. By throwing the corpse of Rufus Quadrant into the water he apparently took little risk. It could not be recognized as White of course, and if correctly identified a mystery would be created that ought to baffle the detectives, however clever they might be. Mr. Barnes felt that he had been fortunate, to learn so much from such unpromising clues.

At his office he found a telegram and a letter, both bearing on the case. The telegram was from Mr. Burrows, and informed him that Morgan had been captured in Chicago, and would be in New York on the following day. This was more than gratifying, and Mr. Barnes mentally praised the young detective. The letter was from Mr. Mitchel, and read:

"Friend Barnes:

"At last I have fathomed the Quadrant mystery. Will drop in on you about noon to-morrow and tell you how the affair was managed. You will be surprised, I am sure.
