The Color of Chaos (Merchant Book 6) by Chris Miller

Sam Merchant finds himself in the middle of a missing persons case as an eye-witness, and gets himself hired on by the cops to look into the weirder side of the crime. The one involving a giant chimera.

As more women go missing, Merchant and Charlie talk to a terrified husband, a shady doctor, and a new mobster in town with a sinister plan. Will they make it through the day, or will the chaos color them finished?
