The Brighton Murders (Camille Divine Murder Mystery 3)

When Camille discovers that her estranged husband, Lord Henry (known as Harry) Divine has given her a boat house in Brighton as part of her divorce settlement, she decides to visit it before the Christmas holidays, anticipating work needing to be done after a long time away from Brighton's delights. She takes her loyal maid, Cecily, with her, and drives down to Brighton in the new motor car included in the settlement. They make a jolly twosome, Camille and Cecily, both looking forward to a few bracing days by the sea, both knowing it will be jolly cold, but still looking forward to a break away from the increasingly busy streets of London.

Camille describes the boat house to Cecily in glowing terms, remembering the wonderful times she and Henry, along with their daughter, Ottilie; then a baby, spent there, playing on the beach and drinking hot chocolate before an open fire in the evenings. Cecily is eager to arrive at the seafront house, but when they enter the rather ramshackle yet quaint dwelling, something awaits them that begins a cycle of bloody murder and an unravelling mystery.
