Her Detective Wolf by Alice Summerfield

Harassed by unknown assailants…
Mechanic Tessa Johnson is up to her neck in trouble, not that anyone believes her. Someone keeps breaking into her house, but nothing is stolen. People are following her. At least, she thinks that they are. And then there’s the corpse in her living room.

Aided by a werewolf with a wicked smirk…
When werewolf Ajax Mytaras stops to save a woman from being kidnapped, he finds the woman that he was made for, his soul mate. Even better, she comes with a mystery. Ajax appreciates that in a woman. As a man gifted with a big Greek family, there’s little enough of that in Ajax’s personal life.

And on the trail of a ruthless murderer.
Tessa and her roommate weren’t particularly close, but as a lightning dragon, Tessa can’t let her murder lie. And as a police detective, neither can Ajax. Together, they team up to find out what’s going on before there’s another murder – namely, Tessa’s.
