The words gave me an idea.

"Suppose," I said, "we could convince Mortimer of that!"

"I don't understand."

"Suppose, for instance, he could be made to believe that you were, let
us say, a dipsomaniac."

She shook her head. "He knows that already."

"What!"

"Yes; I told him I sometimes walked in my sleep."

"I mean a secret drinker."

"Nothing will induce me to pretend to be a secret drinker."

"Then a drug-fiend?" I suggested, hopefully.

"I hate medicine."

"I have it!" I said. "A kleptomaniac."

"What is that?"

"A person who steals things."
