Dr. Fooss lay back in a big, deeply padded armchair and closed his prominent eyes. His pipe went out presently, and now and then he made long-drawn nasal remarks, in German, too complicated for either Lezard or for me to entirely comprehend.

I pondered darkly upon the suggestion. But it seemed unpleasantly like murder.

"Curiosity?"

"Very well; assuming that to be true, what—ah—quality particularly characterizes woman when so beset."

"Ruthless determination."
