Alice Worth and the Elite Death Machine by Lisa Edmonds

What lurks in the shadows has teeth and claws…and has set its sights on Alice Worth.

Mage private investigator Alice Worth and her ghost sidekick Malcolm are back on the case. After a brutal murder in one of its rooms, the manager of a hotel that caters exclusively to supernatural beings hires them to unravel the mystery.
The guest in Room 401 of the Phoenix Inn has gone missing and there’s a bloody corpse in the bathtub that isn’t the person who rented the room. Even with few clues to go on, Alice and Malcolm realize they’re looking for an extremely dangerous predator.
This missing persons case quickly evolves into a battle of wits as well as power as Alice forges an uneasy alliance with a mysterious man who is just as likely to kill her as protect her. As more threats close in on all sides, the case also becomes personal when it dredges up painful memories from Alice’s own past. To save innocent lives, Alice, Malcolm, and Alice’s alpha werewolf partner Sean must face a shadowy enemy created for slaughter and death.
