We Know What You Did

Trade Paperback

The most unforgettable debut crime novel you ll read in 2026

Everyone thinks they know the truth, but the only person who does, is the girl who won't speak.

On the way home from her mother's funeral, nineteen-year-old Odette begins writing a to-do list for her life: Find a job. Find a doctor. Find some friends. The first two items seem doable. The last, less so. She always seems to say the wrong thing to people.

When Odette sees Amos in the museum, she's compelled to speak to him. He looks just like a grandad from a John Lewis advert. He looks lonely like her, too. It turns out she's right, and the two form an unlikely friendship.

Sometimes, Odette feels the incredible urge to wrap her arms around Amos' neck. To hug him so hard that she accidentally squeezes the last breath from his lungs. These thoughts unsettle her, but she knows they are rooted in science. When humans see something loveable, they naturally feel the urge to squeeze, to kiss - even to bite. It's totally normal. Odette is totally normal.

But if she is, then how does Amos turn up dead, Odette covered in his blood? The murder is set to become national news and everyone wants to know one thing: how could this baby-faced girl turn out to be such a vicious killer?

We Know What You Did is an incredibly compelling and tense debut with an unforgettable voice and a protagonist that leaps off the page.
