Meet Lilly Tweed. Former Agony Aunt. Purveyor of Fine Teas. Accidental Sleuth. Organising and catering for a local wedding means the potential to expand into events for Tea Emporium owner Lilly Tweed, and she's pleased to confirm the booking. But as the bride's family let her down one by one, Lilly finds herself taking on more tasks than she'd agreed to. Luckily, she's brought a local café owner on board to provide the food. During the rehearsal, family arguments and spilled wine are the worst catastrophes, but the wedding itself ends in murder. For at the heart of this family lies a dark secret. It's up to Lilly, alongside her friends, Bonnie, the detective in charge of the case, and Archie, the local crime reporter, to solve the case. But while there are motives galore, clues are scarce. When the family suddenly close ranks and the investigation stalls, Lilly is left wondering if blood really is thicker than water, especially when she discovers their secret.
