T is for Trespass by Sue Grafton

A tense and unsettling mystery where danger doesn’t come from the shadows — it’s already inside your home.
 
When private investigator Kinsey Millhone agrees to do a routine background check on a new caregiver, she never imagines she’s about to uncover something terrifying. Solana Rojas seems perfect — competent, compassionate, and dependable — until Kinsey discovers the real Solana was murdered months ago. Now an imposter has taken her place, targeting the vulnerable for profit and control. As Kinsey races to expose the truth, she finds herself in a deadly game of deception with a predator who’s already crossed every line.
 
In T Is for Trespass, Sue Grafton explores the quiet menace of everyday evil with her signature intelligence and empathy. Inspired by real-world cases of elder abuse and identity theft, this novel unfolds through dual perspectives — Kinsey’s sharp, methodical narration and the chilling inner thoughts of her adversary.
 
The result is one of Grafton’s most psychologically rich and socially conscious mysteries, blending investigative grit with moral complexity. Set against the familiar Santa Teresa landscape, the story delves into trust, vulnerability, and the false sense of safety we build around our lives. Both harrowing and deeply human, T Is for Trespass reminds readers why Grafton’s work stands at the top of modern detective fiction.
