Mock was a Christian Chinaman. That is to say, purely for business reasons-for what he got out of it and the standing that it gave him-he attended the Rising Star Mission and also frequented Hudson House, the social settlement where Miss Fanny Duryea taught him to play ping-pong and other exciting parlor games, and read to him from books adapted to an American child of ten. He was a great favorite at both places, for he was sweet-tempered and wore an expression of heaven-born innocence. He had even been to church with Miss Duryea, temporarily absenting himself for that purpose of a Sunday morning from the steam-heated flat where-unknown to her, of course-he lived with his white wife, Emma Pratt, a lady of highly miscellaneous antecedents.

Except when engaged in transacting legal or oilier business with the municipal, sociologic or religious world-at which times his vocabulary consisted only of the most rudimentary pidgin-Mock spoke a fluent and even vernacular English learned at night school. Incidentally he was the head of the syndicate which controlled and dispensed the loo, faro, fan-tan and other gambling privileges of Chinatown.

Detective Mooney, of the Second, detailed to make good District Attorney Peckham's boast that there had never been so little trouble with the foreign element since the administration-of which he was an ornament-came into office, saw Quong Lee emerge from his doorway in Doyers Street just before four o'clock the following Thursday and slip silently along under the shadow of the eaves toward Ah Fong's grocery-and instantly sensed something peculiar in the Chink's walk.

“Hello, Quong!” he called, interposing himself. “Where you goin'?”

Quong paused with a deprecating gesture of widely spread open palms.

“'Lo yourself!” replied blandly. “Me go buy li'l' glocery.”

Mooney ran his hands over the rotund body, frisking him for a possible forty-four.

“For the love of Mike!” he exclaimed, tearing open Quong's blouse. “What sort of an undershirt is that?” Quong grinned broadly as the detective lifted the suit of double-chain mail which swayed heavily under his blue blouse from his shoulders to his knees.

“So-ho!” continued the plain-clothes man. “Trouble brewin', eh?”

He knew already that something was doing in the tongs from his lobby-gow, Wing Foo.

“Must weigh eighty pounds!” he whistled. “I'd like to see the pill that would go through that!” It was, in fact, a medieval corselet of finest steel mesh, capable of turning an elephant bullet.

“Go'long!” ordered Mooney finally. “I guess you're safe!”

He turned back in the direction of Chatham Square, while Quong resumed his tortoiselike perambulation toward Ah Fong's. Pell and Doyers Streets were deserted save for an Italian woman carrying a baby, and were pervaded by an unnatural and suspicious silence. Most of the shutters on the lower windows were down. Ah Fong's subsequent story of what happened was simple, and briefly to the effect that Quong, having entered his shop and priced various litchi nuts and pickled starfruit, had purchased some powdered lizard and, with the package in his left hand, had opened the door to go out. As he stood there with his right hand upon the knob and facing the afternoon sun four shadows fell aslant the window and a man whom he positively identified as Sui Sing emptied a bag of powder-afterward proved to be red pepper-upon Quong's face; then another, Long Get, made a thrust at him with a knife, the effect of which he did not observe, as almost at the same instant Mock Hen felled him with a blow upon the head with an iron bar, while a fourth, Mock Ding, fired four shots at his crumpling body with a revolver one of which glanced off and fractured a very costly Chien Lung vase and ruined four boxes of mandarin-blossom tea. In his excitement he ducked behind the counter, and when sufficiently revived he crawled forth to find what had once been Quong lying across the threshold, the murderers gone, and the Italian woman prostrate and shrieking with a hip splintered by a stray bullet. On the sidewalk outside the window lay the remnants of the bag of pepper, a knife broken short off at the handle, a heavy bar of soft iron slightly bent, and a partially emptied forty-four-caliber revolver. Quong's suit of mail had effectually protected him from the knife thrust and the revolver shots, but his skull was crushed beyond repair. Thus was the murder of Wah Sing avenged in due and proper form.

Detective Mooney, distant not more than two hundred feet, rushed back to the corner at the sound of the first shot-just in time to catch a side glimpse of Mock Hen as he raced across Pell Street and disappeared into the cellar of the Great Shanghai Tea Company. The Italian woman was filling the air with her outcries, but the detective did not pause in his hurtling pursuit. He was too late, however. The cellar door withstood all his efforts to break it open.

Bull Neck Burke, the wrestler, who tied Zabisko once on the stage of the old Grand Opera House in 1913, had been promenading with Mollie Malone, of the Champagne Girls and Gay Burlesquers Company. Both heard the fusillade and saw Mock-a streak of flying blue-pass within a few feet of them.

“God!” ejaculated Mollie. “Sure as shootin', that's Mock Hen-and he's murdered somebody!”

“It's Mock all right!” agreed Bull Neck. “That puts us in as witnesses or strike me!” And he looked at his watch-four one.

“Here, Burke, put your shoulder to this!” shouted Mooney from the cellar steps. “Now then!”

The two of them threw their combined weight against it, the lock flew open and they fell forward into the darkness. Three doors leading in different directions met the glare of Mooney's match. But the fugitive had a start of at least four minutes, which was three and a half more than he required.

Mock Hen took the left-hand of the three doors and crept along a passage opening into an empty opium parlor back of the Hip Leong clubroom.

Diving beneath one of the bunks he inserted his body between the lower planking at the back and the cellar wall, wormed his way some twelve feet, raised a trap and emerged into a tunnel by means of which and others he eventually reached the end of the block and the rooms of his friend Hong Sue.

Here he changed from the Oriental costume according to Chinese etiquette necessary to the homicide, into a nobby suit of American clothes, put on a false mustache, and walked boldly down Park Row, while just behind him Doyers and Pell Streets swarmed with bluecoats and excited citizenry.

Hudson House, the social settlement presided over by Miss Fanny and affected for business reasons by Mock Hen, was a mile and a half away. But Mock took his time. Twenty-five full minutes elapsed before he leisurely climbed the steps and slipped into the big reading room. There was no one there and Mock deftly turned back the hand of the automatic clock over the platform to three-fifty-five. Then he began to whistle. Presently Miss Fanny entered from the rear room, her face lighting with pleasure at the sight of her pet convert.

“Good afternoon, Mock Hen! You are early to-day.”

Mock took her hand and stroked it affectionately.

“I go Fulton Mark' buy li'l' terrapin. Stop in on way to see dear Miss Fan'.”

They stood thus for a moment, and while they did so the clock struck four.

“I go now!” said Mock suddenly. “Four o'clock already.”

“It's early,” answered Miss Fanny. “Won't you stay a little while?”

“I go now,” he repeated with resolution. “Good-by li'l' teacher!”

She watched until his lithe figure passed through the door, and presently returned to the back room. Mock waited outside until she had disappeared.
