is it okay to ask a question in a query?
I've just read this brief on the movie American Psycho
"Patrick Bateman is young, white, beautiful, ivy leagued, and indistinguishable from his Wall Street colleagues. Shielded by conformity, privilege, and wealth, Bateman is also the ultimate serial killer, roaming freely and fearlessly. His murderous impulses are fueled by zealous materialism and piercing envy when he discovers someone else has acquired more than he has. After a colleague presents a business card superior in ink and paper to his, Bateman's blood thirst sharpens, and he steps up his homicidal activities to a frenzied pitch. Hatchets fly, butcher knives chop, chainsaws rip, and surgical instruments mutilate-how far will Bateman go? How much can he get away with?
I began to ponder if someone could write something like this as a query, with those two questions at the end?
It's ok to ask questions in a query if it works. This works, which is not surprising since it's a pitch for a movie and people spend a lot of time and money making sure those pitches entice movie viewers.
What you want to avoid in a query are rhetorical questions: what would you do if? Have you always wanted to do X?
Things that assume a mind-set of the reader are dangerous because agents on the whole are a caustic, jaded lot and we would simply prefer you tell us about the book, and leave the other stuff on the cutting room floor.
