Revenants, revolution...and an amnesiac lady's maid on the loose.

A trip to Europe is all in a day's work for Liz Sharp-that is, until an anarchist throws a bomb at her employer.

As a lady's maid/bodyguard to royalty, Miss Sharp's duty seems clear: protect Princess May, defuse the bomb, and hand over the would-be-killer to the police. At least, that's what the distractingly good-looking Inspector Short advises. But Liz isn't so sure.

No one deserves to be executed and revivified as one of the undead policemen that terrorise Europe-and if that wasn't enough, the bomber, Anton Lupei, claims he and Liz were once lovers. If only she can gain his trust, Anton could be Miss Sharp's only link with a past and family she has forgotten.

As the Orient Express steams from Paris to Hungary, Liz's search for her past threatens to uncover a continent-spanning conspiracy. Why are the anarchists targeting Princess May? Who was Miss Sharp before she lost her memories? And how do you avoid being drained by a very hungry vampire?

It's just as well Liz thought to bring a set of lock-pick hairpins...
