Pieter Posthumus is enjoying a quiet drink when the screaming starts. Marloes, the owner of the guesthouse next door rushes in: one of her tenants has been murdered. Posthumus cannot believe it when she is arrested—for both her tenant Zig's murder and another death years before. Why do people think Marloes is guilty? And why did Zig paint one picture every year—a copy of a Dutch master, but with one peculiar twist? As his investigation progresses he finds that asking questions leads to a truth that's hard to bear.
