Here evidently was no amateur slayer. For, even as the knife-thrust missed its mark, he had resorted to the second ruse, and before Standish could turn around far enough to avert it.

Down went the big man, under the strangle-hold and knee-purchase. With a crash that knocked the breath out of him and dazed him, he landed on his back, his head smiting the sward with a resounding thwack.

His adversary, once more, wasted not a jot of time. As Standish struck ground, the man was upon him, knife again aloft, poised above the helpless Milo's throat.

And it was then that Gavin Brice's flying feet brought him to the scene.

As he ran he had heard a door open. And he knew his warning shout had reached the ears of some one in the house,—perhaps of Claire. But he had no time nor thought for anything, just then, except the stark need of reaching Milo Standish before the knife could strike.

He launched himself, after the fashion of a football tackle, straight for the descending arm. And, for a few seconds all three men rolled and wallowed and fought in a jumble of flying arms and legs and heads.

Brice had been lucky enough or dextrous enough to catch the knife-wielder's wrist and to wrench it far to one side, as it whizzed downward. With his other hand he had groped for the slayer's throat.

Then, he found himself attacked with a maniac fury by the man whose murderous purpose he had thwarted. Still gripping the knife-wrist, he was sore put to it to fend off an avalanche of blows from the other arm and of kicks from both of the assailant's deftly plied feet.

Nor was his task made the easier by the fact that Milo Standish had recovered from the momentary daze, and was slugging impartially at both the men who rolled and tossed on top of him.

This, for a short but excessively busy space of moments. Then, wriggling free of Milo's impeding and struggling bulk, Brice gained the throat-hold he sought. Still holding to the ground the wrist of the knifehand, he dug his supple fingers deep into the man's throat, disregarding such blows and kicks as he could not ward off.
