8. There was something about Dortmunder's 'faithful companion', May, that set her apart from the rest, at least in the first half dozen or so books. What was it?
From Quiz Dortmunder's Crew
Answer:
She was a chain smoker
"She was a chain smoker and kept the current cigarette always propped in the left corner of her mouth; when that area got warm, she knew it was time to start a new cigarette. There was a small callus on the tip of her left thumb, caused by plucking cigarette embers from her lips, but for some reason her fingertips never callused at all. She flipped the half-inch butt from her mouth into the kitchen sink, with one practiced wrist movement, and while it sizzled she took the crumpled pack of Virginia Slims from the waist pocket of her green sweater, shook one up, folded the corner of her mouth around the end and went looking for matches. Unlike most chain smokers, she never lit the new one from the old, because the old one was never long enough to hold onto; this meant a continuing problem with matches, similar to the continuing problem of water in some Arab countries."

By the time of "Drowned Hopes" (1990) May has quit smoking.
