The Adventure of the Incognita Countess

It's the easiest assignment a British intelligence agent could hope for. Lucy Harker needs only see the secret plans of the Nautilus safely across the Atlantic. As German spies are largely a fantasy of newspapers, she anticipates no activities more strenuous than hiding her heritage as Dracula’s dhampir daughter. Then among her fellow Titanic passengers she discovers the incognita Countess Karnstein—and it seems the seductive vampire is in Germany’s service. Can Agent Harker stake Carmilla before her own heart—and her loyalty to the British Empire—are subverted by questions as treacherous as a night-cloaked iceberg?
