MARY HIGGINS CLARK - Moonlight Becomes You

At a party in Manhattan, Maggie Holloway - one of the fashion world's most successful photographers - is thrilled to be reunited with her beloved stepmother. A widow now, Nuala Moore is equally delighted to see her long-lost stepdaughter and invites Maggie to spend a few weeks at her home in Newport, Rhode Island. But when Maggie arrives, she finds Nuala murdered, apparently by a burglar. Heartbroken, Maggie is stunned to learn she had inherited Nuala's stunning Victorian home... and horrified when she begins to suspect that Nuala's death was not random, but part of a diabolical plot conceived by a twisted mind.
 
When Nuala's dear old friend Greta Shipley dies suddenly of supoosedly natural causes, Maggie is convinced that there is a link between these two and other recent deaths among the older women of Newport. What she doesn't realize is that she has now become a target for the killer as well, and that each clue she uncovers brings her closer to an unimaginable fate.
