He was rougher than he realised in wrenching his arm free. She uttered a low moan and covered her face with her hands. Undeterred, he crossed to the door. His hand was on the knob when a door slammed violently somewhere in a distant part of the house.

A hoarse shout of alarm rang out, and then the rush of heavy feet over thickly carpeted floors.

Barnes acted with lightning swiftness. He sprang to the open window, half-carrying, half-dragging the girl with him.

"Now for it!" he whispered. "Not a second to lose. Climb upon my back, quick, and hang on for dear life." He had scrambled through the window and was lying flat across the sill. "Hurry! Don't be afraid. I am strong enough to carry you if the vines do their part."

With surprising alacrity and sureness she crawled out beside him and then over upon his broad back, clasping her arms around his neck. Holding to the ledge with one hand he felt for and clutched the thick vine with the other. Slowly he slid his body off of the sill and swung free by one arm. An instant later he found the lattice with the other hand and the hurried descent began. His only fear was that the vine would not hold. If it broke loose they would drop fifteen feet or more to the ground. A broken leg, an arm, or even worse,—But her hair was brushing his ear and neck, her arms were about him, her heart beat against his straining back, and—Why be a pessimist?

His feet touched the ground. In the twinkling of an eye he picked her up in his arms and bolted across the little grass plot into the shrubbery. She did not utter a sound. Her arms tightened, and now her cheek was against his.

Presently he set her down. His breath was gone, his strength exhausted.

"Can you—manage to—walk a little way?" he gasped. "Give me your hand, and follow as close to my heels as you can. Better that I should bump into things than you."

Shouts were now heard, and shrill blasts on a police whistle split the air.

Her breathing was like sobs,—short and choking,—but he knew she was not crying. Apprehension, alarm, excitement,—anything but hysteria. The fortitude of generations was hers; a hundred forebears had passed courage down to her.
