Rich Girl. The Country Club Murders, #20.5

One secret. Two decades. And a body on the patio. A whirlwind marriage to a French count who wanted her father's money more than he ever wanted her? It's a secret Libba has kept for twenty years. She's never told anyone. Not even Ellison. But secrets can be deadly - and this one is revealed with a knife in his side on Ellison's back patio. Ghislain de Fevre is dead. Quite obviously murdered. And the police think Libba might have killed him.
The truth is tangled in two decades of lies, heartbreak, and unsigned divorce papers. To clear her name, Libba will have to do something she's assiduously avoided - face the worst mistake of her life. Fortunately, she has Ellison, a sharp lawyer, and a pitcher of martinis. Unfortunately, the killer isn't finished.
