April Fool's Day Mysteries/April Fool's Day Crime Fiction

April Fool's Day Mysteries: I love holidays--any chance to celebrate--and that's not an April Fool's joke. Here's a short list full of foolishness and not so foolish mystery and murder! As always, let me know if I've forgotten a title!

The first of April, some do say,
Is set apart for All Fools' Day.
But why the people call it so,
Nor I, nor they themselves do know.
But on this day are people sent
On purpose for pure merriment.
--Poor Robin's Almanac, 1790
