"You will find it quite useless to struggle, Lisbeth," I warned. "Your only course is to remember that he is a growing boy."

"And you are a brute!" she cried.

"Undoubtedly," I answered, bending my head nearer her petulant lips.

"But think of the Imp in bed, lying there, sleepless, tealess, and growing all the while as fast as he can."

Lisbeth surrendered, of course, but my triumph was greatly tempered with disappointment.

"You will then forgive him for the 'ambushes' and cherish him with much tea?" I stipulated, winking away a tress of hair that tickled most provokingly.

"Yes," said Lisbeth.

"And no bed until the usual hour?"

"No," she answered, quite subdued; "and now please do put me down." So I sighed and perforce obeyed.

She stood for a moment patting her rebellious hair into order with deft, white fingers, looking up at me meanwhile with a laugh in her eyes that seemed almost a challenge. I took a hasty step toward her, but as I did so the Imp hove into view, and the opportunity was lost.
