Starred review from May 27, 2019
In McElwain’s outstanding fourth mystery set in Regency England (after 2018’s Caught in Time), the authorities ask FBI profiler and time traveler Kendra Donovan, the American ward of the Duke of Aldridge (one of only two people to know she’s from the future), to look into the strangling murder of English spymaster Sir Giles Holbrooke, who was found lying naked on the floor of an abandoned London church with his tongue cut out. During the autopsy, bizarre markings slowly appear all over Sir Giles’s body, possibly forming a message from the killer. Kendra and her detection team, which includes a Bow Street runner and an irreverent journalist, get on a trail that leads them deep into family jealousies and foreign espionage—and to more ritualistic murders. One of the series’ delights is how Kendra, who operates with a shocking degree of independence for a single woman in the era, must repeatedly find ways to use her forensic knowledge and instincts about homicide that don’t send polite society reaching for the smelling salts. With perfect pacing, McElwain holds the reader’s interest from the first page to the last. Agent: Jill Grosjean, Jill Grosjean Literary.
