Following a personal tragedy, florist Persimmon ‘Simmy’ Brown has moved to the beautiful region of the Lake District. The peace she is searching for is quickly disturbed as a millionaire’s daughter’s wedding ends in tragedy; her brother is found brutally murdered.

As the florist of the wedding and one of the last people to talk to Mark Baxter alive, Simmy slowly becomes involved with the scandalous Baxter family, and is further entangled as she is the prime witness to the another shocking killing.

The chief suspects are the groom and his closely-knit band of loyal bachelor friends. They are all intimidating, volatile and secretive: but which one is responsible?
