Vicki Nelson PI (an ex cop) is on her way home but whilst waiting for her subway train (set in Toronto) she hears a terrifying scream from the other platform, she arrives in time to interrupt the murderer (who flees) but not in time to save the victim who has had his throat brutally ripped out, further victims follow but these have also had all their blood drained! The first victims girlfriend hires Vicki to investigate. Also investigating is Henry Fitzroy the illegitimate child of Henry VIII and five hundred years a vampire. He needs to make sure vampires blend in for he does not want a terrorized city that quickly brings out the sharpened stakes or 20th century laboratory equivalent. And this looks like another vampire has created a child and left it unguided. Both realise the bodies are conforming to a pattern and they meet over the body of the 6th victim, realising there is a lot more at stake than they originally thought the hunt for the killer intensifies, with Vicki working during the day and Henry at night. This is a good story well told and the characters are 3 dimensional (they have their own fears/insecurities and relationships that impact on them). You learn more about Henry through brief flashbacks which sit well within the book. Minor characters enhance the rounded fell of the world and when one in particular died I found myself going "No no not.....". I definitely recommend this book also it has the feel that the next one in the series will be even better.
