Blood Pact by Tanya Huff

Blood Pact - Tanya Huff

From the blurb:


It began with the call no daughter ever wants to get, the call that told private investigator Vicki Nelson her mother had died. Mrs. Nelson's coworker at the Queen's University Life Science Department told Vicki that the cause of death was a heart attack, and that they'd be waiting for her to arrive in Kingston to make the funeral arrangements. But what started as an all too normal personal tragedy soon became the most terrifying case of Vicki's career. For when Marjory Nelson's body mysteriously disappeared from the funeral home, Vicki, her sometime lover and fellow investigator, vampire Henry Fitzroy, and her former homicide squad partner, Detective-Sergeant Mike Celluci, realized that there was something unnatural about her mother's demise. Vicki swore she'd find the culprit, and see that her mother was properly laid to rest. But what she hadn't counted on was that someone at Queen's University seemed determined to keep Mrs. Nelson on the job -- alive or dead!


This is an enjoyable, entertaining, fast-paced mystery/thriller, urban fantasy novel with great characters.  The characters make this series.  The ending was rather unexpected and surprising.



NOTE:  This is book 4 of the series.  Each novel is a contained story, but the characters develop as the series progresses so you really should read them in the correct order.
