I'm currently reading Mrs. Morris and the Vampire by Traci Wilton. This book is the fifth in the Salem B&B Mystery series and was released last month.
With her B&B full of guests Charlene Morris is happy to be celebrating her second Halloween in Salem. While almost everyone is having fun at the Witch Ball, Charlene's friend, Brandy, is none too happy with her daughter's new boyfriend. The older man claims to be a real vampire and certainly seems to have the young woman enthralled. At midnight, the vampire makes a big show and vanishes. Since moving to Salem Charlene has learned that witches and ghosts are real...but vampires? When the undead reappears completely dead Charlene and her handsome ghost try to figure out who the man really was and what he was doing in Salem that got him killed.
