As the Russian army repels German forces from Stalingrad, Maggie Hope takes a much-needed break from spying to defuse bombs in London. Traumatized by her past, Maggie finds herself living dangerously, but when she's called upon to look into the theft of a priceless Stradivarius violin, she can't resist. Meanwhile, there's a serial killer on the loose in London, targeting conscientious objectors. Little does Maggie know that investigating this dangerous predator will pit her against a new evil—and old enemies. In her 9th outing (after Prisoner in the Castle), only Maggie can uncover the connection between the robbery, the murders, and a link to her own past.
