Liza Cody: Backhand (UK 1992)
From the Publisher:
The tangled skein has loose ends both sides of the Atlantic and Anna, glad to leave the muddle of her own life in London, finds herself in Florida, playing a dangerous game whose rules she does not know, and where, under the glitter and the suntans, evil intent flourishes.
