I failed to get into drama school, and my best friend told me I should do stand-up instead. I was always doing gags and voices, so he booked a gig for me without telling me. I only had four days to write it. I did a seven-minute set; the first four minutes were terrible, but the last two were amazing.

I can well imagine that certain writers, even writers that we'd consider today very great writers, may not necessarily have tested highly on IQ just because of their numerical skills, or maybe they may not be very good at memory, and are not particularly good at these kinds of tests.

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.
