"We'll make a list. A list of all the people and things we see that are suspicious. And then . . . we'll investigate them."

Twelve-year-old Miv is panicking. Life has been complicated since her mom got sick, and now her dad is talking about wanting to move their family away from the town Miv has lived in her whole life—because of the murders. Young women are dying, everyone is afraid, and no one knows who the culprit might be.

But as far as Miv is concerned, leaving Yorkshire and her best friend Sharon simply isn't an option, no matter the dangers lurking round their way; or the strangeness at home that started the day Miv's mum stopped talking. Perhaps if she could solve the case of the disappearing women, they could stay after all?

So, Miv and Sharon decide to make a list: a list of all the suspicious people and things on their street. People they know. People they don't. But their search for the truth reveals more secrets in their neighborhood, within their families—and between each other—than they ever thought possible. What if the real mystery Miv needs to solve is the one that lies much closer to home?
