When I first heard about the 2012 Edgars Nominations, I had read surprisingly few of the nominations in Juvenile, Young Adult, and short stories. Wouldn't you know that the one Young Adult book I didn't get around to reading was the winner!
Best Young Adult:
Best Short Story went to "The Man Who Took His Hat Off to the Driver of the Train" - Ellery Queen Mystery Magazine by Peter Turnbull (Dell Magazines).
