The body of a prostitute is found at Glasgow s Queen Street Station her hands pointing towards her feet placed as if in prayer a small flower pressed between the palms. Psychologist Solomon Brightman is called to assist DCI Lorimer in the murder hunt with the hope that his lateral thinking will shine a light on the case from a different angle. But before any conclusions can be drawn the body of a nurse is discovered at The Grange a private clinic. Aside from the careful arrangement of the corpses there is no obvious connection between the victims; Lorimer & Solomon are still very much in the dark. Then a third body turns up & it seems increasingly clear that they have a serial killer on their hands.
