Can a stolen violin lead secret agent and spy Maggie Hope to the latest serial killer terrorizing London during World War II?

Maggie Hope started out as Mr. Churchill's secretary, but now she's a secret agent—and the only one who can figure out how the missing instrument ties into the murders.

London. December, 1942. As the Russian army repels German forces from Stalingrad, Maggie Hope takes a much-needed break from spying to defuse bombs in London. But Maggie herself is an explosion waiting to happen. Traumatized by her past, she finds herself living dangerously—taking huge risks, smoking, drinking, and speeding through the city streets on a motorcycle. The last thing she wants is to get entangled in another crime.

But when she's called upon to look into a stolen Stradivarius, one of the finest violins ever made, Maggie can't resist. Meanwhile, there's a serial killer on the loose in London, targeting Conscientious Objectors. Little does she know that investigating this dangerous predator will pit her against a new evil—and old enemies. Only Maggie can uncover the connection between the robbery, the murders, and a link to her past.
