I Thought It Was You

It looked like a running accident. Until she saw the photo.
Until the note read: I thought it was you.

Dr. Natalie Greystone has spent her life examining the dead with clinical precision and locked-down calm. But when the body of a woman turns up at the edge of the trail she used to run—similar build, similar stride—her professional distance starts to fracture.
Then the photograph arrives: grainy, off-kilter, and chilling. And scrawled in one corner are the words: I thought it was you.
As the case tightens around her, Natalie is forced to confront a tangled web of grief, jealousy, and misdirected blame: Adam, the analyst who disappeared just after the murder. Kiera, a colleague whose envy runs deeper than history. And Will, the quiet lab tech with more access than anyone realized.
Because someone mistook that girl for Natalie.
Or someone wanted her dead.
And Natalie doesn’t know which is worse.

Eerie, atmospheric, and razor-tensed, I Thought It Was You is a psychological thriller about obsession, proximity, and the quiet terror of realizing someone’s been watching you… for a very long time.
