Getting a diagnosis of HIV is bad enough, but even worse if you know you have no risk factors. At the start of Lenti, we meet a young man deliberately, but unknowingly, infected with HIV. As more cases occur, Inspector Bill Painter is sent to investigate. Painter is an old-school policeman with a love of jazz and a belief in police procedure. He is not comfortable working with women, but has a female superior officer and now a new female Sergeant both of whom, unlike him, are university graduates. Painter is married, but distracted by recurring doubts about a recent brief affair. Guilt occupies his thoughts as he tries to work out when, why and by whom the crime was committed. He seeks the help of a psychologist to profile the character of a possible perpetrator which takes the pair into the heart of academia. Will they be able to identify him/her in time to stop an epidemic of cases in London? About the Author Professor Griffiths has an international reputation in the prevention and treatment of virus infections. In a dramatic change of focus from this medical practice, he provides an intriguing story that weaves authentic scientific information into the lives of fictitious characters to imagine what might happen if someone trained in medical virology used their knowledge for malign purposes.
