Did you know?

In 1930, Donald Gordon, a book reviewer for News of Books, needed to come up with something to say about a rather unremarkable mystery novel called Half-Mast Murder. "A satisfactory whodunit," he wrote. The relatively new term (introduced only a year earlier) played fast and loose with spelling and grammar, but whodunit caught on anyway. Other writers tried respelling it who-done-it, and one even insisted on using whodidit, but those sanitized versions lacked the punch of the original and fell by the wayside. Whodunit became so popular that by 1939 at least one language pundit had declared it "already heavily overworked" and predicted it would "soon be dumped into the taboo bin." History has proven that prophecy false, and whodunit is still going strong.
