A Perfect Day For Dying

Description for A PERFECT DAY FOR DYING by Joyce Christmas:

When a posh party in the Caribbean arranged by Lady Margaret's good friend and ne'er-do-well Paul Castrocani, for wealthy Lord Fairfane, provides the setting for two murders, Lady Margaret flies to the scene. An expert in upper-crust mruder, she poses as a party-goer to ferret out the killer. Her snooping uncovers messy little secrets from the Farfaine past, as blackmail, black magic, and deadly rumors expose the dark side of paradise....

This is #7 in A Lady Margaret Priam Mystery.
