"Come then. You're a brave man, Mr. Thode!" Gentleman Geoff led the way swiftly across the patio to a little door half hidden in the creeping vines. But even as he laid his hand upon the rusty bolts, there was a storm of feet in the alley and a rain of shot pattered against the outer wall.

Gentleman Geoff stepped back with a gesture of defeat, but Thode cried desperately:

"I can cut my way through them. I must, Man! Open the door!"

Instead, his companion shot the hasp of a small oblong look-out on a level with their eyes, and Thode beheld the alley choked with figures, their carbines bristling and maniacal, distorted faces pressed close.

"No use." Gentleman Geoff snapped the slide in place as a stray bullet whistled past their ears. "It's too late. Even had you gone when Sam first came, they would have cut you down in the plaza. You can only lend a hand here."

Wordlessly, Thode stumbled back beside him to the gambling-room. That which but a moment before had seemed like a wild, purposeless stampede had resolved itself into an unorganized but determined defensive. Few of the men had departed, those few who had ridden in from nearby haciendas where unwarned families waited in ignorance of the menace sweeping down upon them from the hills.

Thode worked with heaving chest and straining muscles, but his brain was singularly clear and his observation acute. Gentleman Geoff seemed to be everywhere at once, urging, exhorting, commanding. The mozos, their yellow faces gray, were huddled in a corner, clucking like dismayed fowl at the approach of a storm, but a word from Billie sent them scurrying for the store of guns and ammunition.

She, too, it was who opened the door of an inner room where a group of disheveled women, their faces ghastly beneath the cheap paint, cowered about a roulette-table, and ranged them behind the shelter of the stout mahogany bar, seeing to it that each was armed.

Her calm face in the tumult and smoke and dust seemed etherialized, glorified to the wondering eyes of the young engineer; the marvel of her strength and courage shone forth like a radiance, imbuing even the panic-stricken Celestials with a spirit of defense.

Thode's eyes were smarting, his veins on fire and in his nostrils the reek of powder mingled with a strange, new, sweetish odor. The table-top on which he stood was slippery where Rufe Terwilliger had doubled up beside him and rolled to the floor. Others were falling, too, stumbling and clutching vainly for support, but Billie's slim white figure still stood unwavering beside her father and Thode turned grimly to his task.
