Gone without a Trace - Grover Denise Swank

Maddie Baker hasn't seen Detective Noah Langley since he ghosted her a month ago, but now she needs his help to find a missing woman.

When Maddie Baker offers a self-defense course, a terrified young woman asks her for private lessons to escape a chokehold. Maddie readily agrees to meet Amy the next morning, but when she doesn't show up, Maddie becomes concerned.

She enlists the help of Detective Noah Langley and his partner Lance Forrester. Since it's not an official investigation, and the only thing they know about her is her first name, it's not long before their hands are tied.

Besides, Noah has a dilemma of his own. A rash of home burglaries has taken a disturbing turn. Noah and his partner Lance feel pressed to catch the burglars before someone is physically assaulted...or worse.
