Night Train to Cherbourg — Jennifer Quail

Joszef Kiraly was born a lord in the Austro-Hungarian Empire, and he died one in war . . . . but in a world where vampires, shape-shifters and loup-garou move freely in the highest circles, death can be only the beginning. A hundred years later, he makes his unliving and amuses himself by solving crimes, great and small and sometimes even ones that appear out of nowhere. En route via the night train from Vienna to Cherbourg, Joszef expects nothing but a routine trip, until a young woman with a serious problem forces her way into his compartment. She's alone, she's afraid, she's being chased through the train by two men trying to catch her, and she is definitely telling a lie. With time to kill and a lovely young woman practically dropped in his lap, Joszef is on the case. If you are looking for a vampire more akin to Lord Peter Wimsey than Lord Rutheven look no further than Joszef Kiraly, Gentleman and Vampire.
