Tall, red-haired Liz Connors is a former college professor turned crime writer who is expert at digging up details even the cops couldn't find. This time she has to: her lover, Detective Lieutenant Jack Lingemann, is being held without bail on a murder charge, and all Boston is crying for his head.
She enlists the help of two reporters and two cop-friends to dig up information that lies buried in the annals of Cambridge history. Her investigation discovers links between a series of violent attacks on women, a dishonest real estate tycoon, and a tragic fire in a tenement; all are clues to the real killer's identity. Until Proven Innocent is a galvanizing puzzle and a delight.
