Lowen Ashley on the brink of financial collapse. Therefore, she accepts an offer from the husband of the famous writer Verity Crawford to become a co-author of her novel, since she does not get out of bed after the accident and does not react to anything. Among the drafts of the new book, Lowen accidentally finds an unfinished biography - one that Verity certainly did not intend to make public. The text is full of madness, and it contains a confession of murder. At first, Lowen hesitates to tell her husband Jeremy, for whom she feels sympathy. But when Lowen begins to suspect that Verity is faking illness, and at night walks around the sleeping house, she realizes that she must find the truth in the name of her own safety.
