When a bright young man teams up with a glamorous femme fatale, the identity of a murderer won't be the only secret they'll unmask.

London, 1922. Between gallivanting in his Rolls-Royce and darkening the doorways of London's hotspots, Lord Reginald "Rex" Bankes-Fernsby has almost succeeded in banishing the battlefield nightmares that plague his sleep. Pity he can't say the same about that nagging lack of direction in his life.

If only he were like his best friend Freddie—self-assured, suave, and up to his ears in secrets. But when Freddie is murdered, Rex doubts the verdict. Was Freddie really cut down while up to no good, or was he killed in the line of duty?

Rex turns to the only person in London capable of helping him find out—Theodora Laurent, London's most notorious femme fatale and Freddie's last known lover. Theodora has a hundred reasons to let sleeping cats lie, but those disappear into the aether when Rex shows up on her doorstep and someone takes a shot at her head. Together, they're catapulted into a race for their lives, where identifying the murderer is their only hope for survival.

There's just one problem: Freddie wasn't the only one keeping secrets. If Theodora isn't careful, Rex's search for the truth could send her cunningly constructed empire falling like dominos.

Murder, I Spy is the first book in this exciting 1920s historical mystery series. Includes bonus novella Murder at the Front.
