London 1899. The Museum Detectives Daniel Wilson and Abigail Fenton have been contacted by the curator of the National Gallery. He is getting in touch at the request of the artist, Walter Sickert, famously suspected of being Jack the Ripper for many years. The dead body of a young woman, who had been an artist’s model, has been found at the back of the Gallery. She had been eviscerated and Sickert has been arrested on suspicion of her murder.

Although he is soon released, when a second similar murder occurs, Sickert is once again implicated. The murders are copycats of the original Ripper murders, but the details of those crimes were publicised so heavily in the newspapers at the time that most people would know them. Sickert insists he is innocent so who is trying to frame the famous artist? Wilson and Fenton have their work cut out .
