What happens when sisters go undercover to investigate a sex club linked to the murder of their employer, and they discover their mother may have ties to it? SUNDAY BEST, an engaging comic mystery by Ann Lineberger, explores the lengths people will go to indulge their fantasies while preserving their secrets.

When real estate and publishing mogul Walter Bloom is murdered in the postcard-perfect Connecticut town of Longshore, his brother and business partner, Charles, is determined to discover who is responsible. Walter had a public history of sexual harassment and a private involvement with sex clubs. Charles is convinced Walter’s murder is related. When the local police department’s investigation stalls, he enlists the help of his employees, including sisters Lauren Mark and Brooke Edwards, to help infiltrate the Swingers’ groups Walter favored. Together, they discover a comically warped and perverse subculture eerily connected to the wacky alternative church Lauren and Brooke’s clairvoyant mother co-founded in their youth.

Laced with humor and biting social commentary, SUNDAY BEST is an inventive and absorbing murder mystery that looks into the world of sex clubs, alternative religions, and clairvoyants as a study of selling hope in contemporary America. Fans of Liane Moriarty’s Big Little Lies will find an intriguing mystery that combines female-driven detective work, tantalizing behind closed-door reveals, and the exploration of female aggression uniquely balanced by a cast of endearingly flawed characters and mystical escapades that will resonate with fans of Liane Moriarty’s The Hypnotist’s Love Story.
