Again that swift, silent progress through the night.

Once Sam whispered: "I guess we were stung. I can't hear anything back of us any more, can you?"

"No," said Martha. "But stung or no stung, keep a-goin'. We ain't takin' no risks."

Ellen Hinckley slept fitfully, but even in her waking moments she was not aware of the dangers the others had feared.

"Let her rest," Martha meditated. "After she's made a clean getaway, she'll have all that's comin' to her, in the line o' excitement an' strain. I don't believe'm when he says she ain't all there in the upper story. But that's not meanin' I think she's furnished as handsome as some. She may have all her buttons, an' yet not be the brainiest party I ever come in contract with. Why didn't she up an' open her mind an' give Buller a piece o' it long ago? There's many things a married woman's got to shoulder, God knows, but chas*tise*ment, hot off'n his griddle, as you might say, not on your life, even a married woman needn't stand, much less a unmarried maiden-girl. It ain't decent. If a man oncet took the strap to me, I'd fix'm so's the doctor'd have to hunt for the buckle o' his belt behind his internal workin's, in back among his spine. An' I'd be proud o' the job."

When they were within about five miles of Burbank Sam gave a low whistle.

"I was wonderin' if you heard it too," Martha responded promptly. "Firstoff I thought 'twas my imagination, but it ain't. Somethin' certaintly's follain' along in our tracks."

"The first was a false alarm. So may this be," said Sam.

"Sure. But, could you speed up some? Just for luck?"

Presently Martha heard another sound.
