Audiobbook "Dying for Mercy" by Mary Jane Clark

To get some much-needed rest out of the public eye, Eliza Blake, anchor of TV's premiere morning news show KEY to America, rents a charming carriage house in Tuxedo Park, New York.
Behind the private park's stately stone gates, sprawling architectural masterpieces and picturesque gardeners' cottages decorate the rolling, naturalistic landscape. Even before she can move in, Eliza is invited to an unusual party to celebrate the feast of St. Francis Assisi and, before the festivities are over, the serenity of the secluded enclave explodes as one of the Park's revered citizens is found dead -- a grotesque suicide which is only the first act in a macabre and intricately conceived plan to expose the past crimes of some of the town's residents.
Eliza and her KEY News colleagues soon learn that Pentimento -- a gloriously restored mansion nestled in the Park's fairytale setting -- is, in effect, a giant "puzzle house," filled with ingenious clues hidden in its fireplaces, fountains and frescos that lead them, first, to suspicious locales throughout the Park -- and, then, one by one, to the victims of a fiendish killer!
As Pentimento gives up its many secrets, it becomes clear that someone wants to prevent one last mystery from coming to light and that no amount of wealth or privilege will keep the threatened residents of Tuxedo Park safe. And as Eliza Blake unearths one final secret, she will come face to face with a murderer who thinks that some puzzles should never be solved.
