“I just wanted to tell you,” was his greeting, “that I am going to disappear. Don’t look for me. I will discover myself when the time comes. I’m going to lose myself up in Chinatown, for the solution of that story is there, and I’m not coming until I’ve landed something and choked off the side remarks of the Times and Herald outfit, if I stay there for the balance of my natural life. The police can hang as they please to their hoary old dogma that a ‘hop head’ never commits murder. Just because they’re so positive, I am going to take the other tack; at least until I have proved their theory to my own satisfaction. There isn’t a man outside the frequenters of this quarter knew of that subcellar and that’s the theory I am going to stick with now. Keep in pretty close touch with the office so I can get you in a hurry if anything turns up. Good-by.”

In another moment he was walking rapidly up Washington Street to disappear down Dupont, out of sight for three days.

The story had run eight days and a dearth of fresh angles had thinned it out a trifle, when, on Saturday evening, along about ten o’clock, as I hung around the local room hoping against hope for a call from Lanagan, it came.

“Meet me in front of old St. Mary’s,” he said, shortly, and I thrilled instantly with that same premonitory tremor that always came over me when the climax was on. I sped down Kearney Street and in the shadow of the church steps picked him up.

“Dorrett is watching me,” he said. “He’s been covering me for days.” Dorrett was the oldest special policeman in Chinatown and generally held to be a “leak” for the Herald through personal friendship for a former police reporter, now city editor of that paper. In such fashion do papers develop their “sources” of news. “I have one clue that may be the key to the solid brick wall we have been up against. And I am not going to lose that key to the Herald via Dorrett,” concluded Lanagan, as he suddenly stepped fully into the glare of the gas street lamp on the corner just as Dorrett sidled up. I saw that Lanagan had deliberately exposed himself.

“Really, Dorrett,” he remarked in that sinister tone he could assume so well on occasion, “some of these days I shall actually trip over you if you persist in blundering beneath my feet. You might fall quite hard in that case and hurt yourself. However, just tell Cartwright” (city editor of the Herald) “that I am going to hand him a package of nitroglycerin right on your own particular little bailiwick, will you? Please run along now, like a good little special policeman, because we are going to lose you—thusly.”

He turned on his heel and ran for a California Street car just lumbering past us up the hill and I followed suit. After a few blocks he crossed through the car and dropped off on the other side. Scouting cautiously back toward Chinatown by way of Washington Street, drifting along with eyes wide for Dorrett, we finally made Ross Alley, where Lanagan stopped for a fraction of a second at the wicket of the gambling house at No. 8.

At that time it was a strict rule of the gambling “joints” that a white man could not enter. Personally, for all of my four years’ dubbing around on police, I never had been able to enter a Chinese gambling house when the play was on. Yet the lookout flashed one glance at Lanagan, grinned yellowly and ingenuously, and the massive solid oak door before us swung noiselessly open and we passed quickly through. As it shut behind us I heard a faint click-click, and glanced back. Three separate two-by-four scantlings, heavily re-enforced with iron, had dropped back into their sockets. The door was as solid as a concrete wall against the axes of the Chinatown squad; the theory being that by the time the squad had the door battered down, the players had departed through some secret runway.

“Melodrama?” laughed Lanagan at me. “But I had to come by the back door, as it were. I wouldn’t like to have any stray police or reporters or Dorrett suspect I was about to interview the man I am. They might smell a rat, possibly. We are more isolated among these hundred Chinks, gambling their fool heads off, than we would be in one of Leslie’s dark cells.”

We passed directly through the long room with its eight high tables, at each of which ten or a dozen impassive Celestials, with chopsticks, beans, and teacups, stood engaged in the contraband pastime of fantan. At a table or two a pie gow game was running, and in a corner dominoes. The air was so heavy and heated that I felt the perspiration starting in an instant. The Chinese gambler, if he is winning, sticks in that thick atmosphere for hours at a time.
