Uneasy Prey (Zoe Chambers Mysteries #6)
Annette Dashofy

Zoe—in spite of Pete’s objections—takes it upon herself to act as protection detail after the con men, disguised as water company employees, set their sights on Zoe’s beloved former landlady. It’s a decision that eventually puts Zoe in harm’s way.
With Zoe already recovering from one close call, Pete must race against time to stop the crime ring—and a dangerous killer—before they strike again.
