Human remains yield vital facts in London University's forensic pathology department, where Professor Leo Dalton, Dr. Harry Cunningham and forensic anthropologist Nikki Alexander examine gruesome evidence in four new cases. Does Leo want justice or revenge? for the deaths of his wife and child? Race to the scene of a drive-by shooting littered with dying gang members. You'll wonder why kidnappers killed their victim before they delivered the ransom note, and what connects four apparently unrelated suicides. Emilia Fox stars in the award-winning BBC crime series, with "complex characters, smart plotting and clever direction" (Independent).
