Mark Williams-Thomas's investigation uncovers another Glasgow murder that bears all the hallmarks of suspected serial killer Angus Sinclair. There is just one problem - unlike the murders of Anna Kenny, Agnes Cooney and Hilda McAuley, this crime has already been solved. A week after 37-year-old baker Frances Barker's body was discovered, lorry driver Thomas Ross Young was arrested, and was subsequently jailed for life. The investigator tries to establish whether the police got the wrong man - or if there could be another explanation. Last in the series.
