Josephine Tey (aka Gordon Daviot, aka Elizabeth MacKintosh) was less prolific and more private than some of her peers, but her fans have kept nearly all her mysteries in print since their first publication. As Francis Wheen notes, her books regularly ignored the usual crime fiction formulas, subverting expectations in interesting ways.

Her main detective character, Inspector Grant, first appears in The Man in the Queue, a novel joining the US public domain in 27 days. #PublicDomainDayCountdown
