Camels and Corpses — G.K. Parks

The crime ring is catering to an international car broker, Reginald Barlow. He's mysterious and dangerous. Before the final cars are boosted, a few more vehicles are added to the list, along with some additional players. Apparently, Barlow is involved in more than just high-end car thefts, especially since one of the stolen vehicles is found at the scene of a double homicide. 

The deeper Alex digs, the more complicated the case becomes. Instead of just a few GTAs, there is a killer for hire on the loose, and a cop from her past ends up in his crosshairs. Alexis Parker must hunt the hunter. He's eluded Interpol and the European authorities. Now he's here. His identity is unknown. His contracted targets are unidentifiable, and his method for killing is gruesome, dehydrating and then drowning his victims so their remains resemble human soup. The only name they have for him is the Camel. It's a battle of wits that requires Alex to be at the top of her game if she hopes to survive.
