BBCOne show creator of Death in Paradise, Robert Thorogood delights in giving the Christie-mystery a busy-body twist. Judith (our favorite skinny-dipping, whiskey-sipping, crossword puzzle author), along with Becks the vicar's wife, and Susie the dogwalker find themselves in a head-scratching, utterly clever country house, locked-room murder mystery.

Holiday festivities are now January doldrums when Judith gets a call--Sir Peter Bailey, a prominent Marlovian is inviting notable citizens to his house the day before his wedding to celebrate.

Judith decides to go--after all, it's a few houses up the Thames and free champagne, for sure. During the party, a loud crash inside stops the festivities. The groom-to-be has been crushed to death in his study. The door was locked from the inside so the police say suicide, obviously.

Friends. Sir Peter cannot be left for dead like that...Judith and the Marlow Murder Club are on the case.
