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.
