"A reluctant ex-spy with demons of her own, Elinor finds herself facing down one of the most dangerous organized crime gangs in London, ultimately exposing corruption from Scotland Yard to the highest levels of government"-- Provided by publisher

Post-World War II Britain, 1947. Forty-one-year-old "Miss White," as Elinor White is known, lives quietly and privately in Shacklehurst, a village in Kent, England. The residents have no way of knowing how dangerous Elinor's war work had been, or how deeply their mysterious neighbor continues to be haunted by her past. Susie, the child of farmworker Jim Mackie and his wife, Rose, breaks through her ice demeanor. But Jim has something in common with Elinor: he, too, is desperate to escape his past. When the powerful Mackie crime family demands a return of their prodigal son for an important job, Elinor assumes the task of protecting her neighbors. -- adapted from Goodreads info
