Fire Must BurnFire Must Burn

London, 1947. Iris Sparks is eager for a break after recent turmoil, but peace has to wait. Her old intelligence boss recruits her and her partner, Gwen Bainbridge, for a covert mission involving Iris's former Cambridge friend, Anthony Danforth--now suspected of spying for the Soviets. To uncover the truth, they must draw Tony into hiring their matchmaking service so an undercover agent can get close to him. Reluctant but loyal, Iris agrees, determined to clear Tony's name if she can--or expose him if she must. Being a spy, she learns once again, is never simple.
