"The devils have come back!" Cleek cried as he put on greater speed than ever. "There's not a moment to be lost. Lord send she's safe. Hurry, man, for God's sake, hurry!"

But there was no need to tell Constable Roberts to "hurry," for fully alive now to the urgency of the case he was already panting his way up the front steps.

"Locked," snapped Cleek as his fingers felt for the handle. "Get back to the rear. You go to the right. I'll try the ball room window."

Switching on his heel, he was gone before the ponderous body of Constable Roberts had recovered its breath. It was pitch dark now, and once out of range of the brilliant motor-lamps, the house was shrouded in a mantle of blackness. But Cleek had his electric torch and as he sped swiftly on his course he swung its light against shrubs and windows.

Turning the corner of the wall, he came within sight of the ball room window once more and reached it in the twinkling of an eyelash. To his dismay he found it not only locked, but what was even more terrifying by reason of its significance, shuttered and barred from within!

Cleek gave vent to a little cry indicative of mild despair and brought out his torch, letting its tiny searchlight fall upon the smooth lawn in front of him. It could do little more than throw a weak circle of light a few feet into the depths of the trees leaving all beyond and upon either side doubly dark in contrast. But for this Cleek cared nothing, for even as the light streamed out and flung that circle into the impinging mist, there moved across it the figure of a woman with a scarf of gold lace thrown over her head, from beneath which fell a shower of dark, unbound hair. It effectively concealed her face, and almost covered her shoulders wrapped in scarlet satin.

Satin in March! And a woman! She was the second woman he had seen cross the lawn that night, the one an hour or so ago, in white, and now this one in scarlet. The thing was so uncanny, so totally unexpected, that Cleek's brain positively reeled. In a flash she was gone.

He turned to follow in pursuit, but as he switched on his heel, it was to come face to face with the panting, breathless figure of Mr. Roberts.

"Ev—every door—fastened, sir," he said, his breath coming in great gasps. "What on earth's the matter, I dunno. But that's the gospel truth, and I'll swear to it!"

"Nothing else to do but to attack the front then," said Cleek. "Come on, Constable. No time to be wasted."
