Selected and introduced by Richard Glyn Jones. The first in its series -- its success led to a similar volume, Solved, a few years later -- featuring fiction writers on real cases; includes Edmund Pearson, James Thurber, Dorothy L. Sayers, and others.
The paperback looks previously owned -- edgewear all around; a sticker and sticker ghosts on the front cover, which is a bit wavy; a couple of crunched pages -- but the spine is uncracked. A great reading copy...or park it on the back of the toilet tank, I won't tell anyone.
