I’m in your house. I’m in your head. And now I know your secret.

Elle Fielding is floundering. Her once perfect marriage is falling apart and she’s on the verge of losing her book deal—and, by extension, the dream home she’s poured her savings into. As her finances dwindle, Elle decides to rent out her Cornish home on Airbnb. Just this once.

But when she returns home after a writer’s retreat away, nothing feels right. There’s a new coldness. A shift in the atmosphere. The prickling feeling that someone is watching her every move from the shadows. Maybe it’s all in Elle’s mind? And yet every threat seems personal. As if someone has discovered the secrets that keep her awake at night. As fear and paranoia close in, Elle’s own home becomes a prison. Someone is unlocking her past—and she’s given them the key.

With Hitchcockian dexterity, Lucy Clarke unlocks one of our most primal fears in this mind-bending thriller about the horrors that lurk behind closed doors. In a world where technology has brought us closer to both loved ones and strangers, You Let Me In is a disquieting and nightmarishly intense addition to Lucy Clarke’s searing oeuvre.
