I Can See in the Dark [EPUB ebook] 

Riktor doesn t like the way the policeman comes straight into the house without knocking. He doesn t like the arrogant way he observes his home.The policeman doesn t tell him why he s there, and Riktor doesn t ask. Because he knows he s guilty of a terrible crime. But it turns out that the policeman isn t looking for a missing person. He is accusing Riktor of something totally unexpected. Riktor doesn t have a clear conscience, but this is a crime he certainly didn t commit.
