As one rising Apache fell wounded, the other mobsters dived for cover. With sweeping strides, The Shadow gained the door, and his sardonic laugh was loud with mockery and menace.

As The Shadow's hand pressed the knob, the door crashed inward, and a squad of gendarmes burst into the place. Coming to rescue a helpless American, they had heard the gunfire. The Shadow stepped back as the door burst. The gendarmes were hurtling upon him. His right arm swung with terrific force as The Shadow leaped among the officers.

Two gendarmes staggered. Their hands slipped from the black cloak. Diving forward, The Shadow broke loose and sprang to the street.

The Apaches had been quick to meet the double emergency. Their guns were barking as The Shadow swung his way through the gendarmes. They sought to slay the man in black, and to withstand the attack of the law.

Their first purpose failed. The hail of bullets was too late to thwart The Shadow's escape.

Gendarmes were falling; but others, dropping to the floor, blazed away at the mobsters. The Apaches were outnumbered. Those who were able, scurried to the corridor and fled.

With the mob subdued, gendarmes rushed to the street and scattered everywhere in search of the man who had baffled them. But in the darkness that reigned over that quarter of Paris, a man in black could make himself invisible.

Darkness shrouded the form of The Shadow. He was nowhere to be found.

While the gendarmes still persisted in their search, the dignified American reappeared in Suite 15 of the Hotel Barzonne.

His face retained its calmness; there was no hurry in his action as he opened the drawer of the steamer trunk and removed the clippings and the typed sheets that referred to Herbert Brockley. In a blank space, the quiet man wrote the name of Louis Bargelle. The last of Brockley's slayers was gone. Methodically, the American tore the sheets and clippings. He laughed — and his laugh was an echo of those taunting jibes that had sounded within the walls of the Poisson d'Or. The next morning, two Parisian detectives were going over a report of the battle at the Apache dive. They were discussing the deaths of certain criminals — among them Louis Bargelle — when an attendant entered. He was carrying a tightly wrapped paper.
