“Instruments of Darkness” by Imogen Robertson will be the first book for 2020 in the Library’s popular “It’s a Mystery” series. The discussion will take place on Tuesday morning, January 28th at 10 am in the All Saints Episcopal Church’s second-floor library. “Instruments of Darkness’ is a fast-paced historical mystery starring a pair of amateur late eighteenth-century sleuths with razor-sharp minds. When Harriet Westerman, the unconventional mistress of a Sussex manor, finds a dead man on her grounds, she enlists reclusive anatomist Gabriel Crowther to help her find the murderer. Moving from drawing room to dissecting room, from dark London streets to the gentrified countryside, this is a gripping tale of the forbidding Thornleigh Hall and an unlikely forensic duo determined to uncover its deadly secrets. The Library’s book discussions are open to all. Copies of “Instruments of Darkness”are now available.
