In this third installment of The Mistress Diaries, the bawdy, naughty adventures of Amaris Martin, ambitious career mistress to a millionaire, Amaris’s lover Leon loses at a high-stakes Vegas poker game, and a night with Amaris is part of the bet. Rather than being outraged, Amaris is delighted—the man who won her is very sexy. . . and even richer than Leon! Approaching the night as a potential job interview, Amaris is dismayed to discover the guy’s already got a mistress who’s not too keen on the ménage a trois he has in mind. But by the end of the night, Amaris is sure she’s got herself a new benefactor…until she wakes up the next morning to find his dead body in her bed, and her rival claims Amaris killed him.
