Faith Hill

Mysteries include so many things: the noir novel, espionage novel, private eye novels, thrillers, police procedurals. But the pure detective story is where there's a detective and a criminal who's committed a murder and leaves clues for the detective and the careful reader to find.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
