The Third Catrin Sayer Mystery. Janis Mitchell, a second-year student at Falmouth University in Cornwall, receives a shocking image ‘hacked’ into her Facebook page, one of her being viciously assaulted at knifepoint. Janis realizes that it is probably derived from a session where she modelled for a figure-drawing class at a nearby college. Worked into the image and partially buried is a vase, but no-one understands its significance. Detective Sergeant Catrin Sayer with the Art Crime Unit at New Scotland Yard is asked to help, based on her experience as an artist rather than as a formal member of the investigation team. She is drawn further into the strange case with the appearance of a second image of the student hacked into the website of the Tate Art Gallery.
