When Marlene Cowley hires Spenser to see if her husband Trent is cheating on her, he encounters more than he bargained for: not only does he find a two-timing husband, but a second investigator as well, hired by the husband to look after his wife. As a result of their joint efforts, Spenser soon finds himself investigating both individual depravity and corporate corruption.It seems the folks in the Cowleys' circle have become enamored of radio talk show host Darrin O'Mara, whose views on Courtly Love are clouding some already fuzzy minds with the notion of cross-connubial relationships. O'Mara's brand of sex therapy is unconventional at best, unlawful--and deadly--at worst. Then a murder at Kinergy, where Trent Cowley is CFO, sends Spenser in yet another direction. Apparently, the unfettered pursuit of profit has a price.With razor sharp characterizations and finely honed prose, this is Parker at the height of his powers.
