Professor Jasper Tempest (Ben Miller) precisely calibrates and structures every aspect of his life. Impeccably dressed and meticulously punctual, he lectures daily at the Cambridge Institute of Criminology, teaching students imaginatively, if pedantically, about the science of crime. And each evening, he returns home to his apartment, which is as sterile and systematically ordered as a science lab. Thanks to this strictly regimented approach, his OCD and germaphobia are under control. But Professor T's buttoned-down world is slowly undone when he is persuaded by one of his former students, Detective Sergeant Lisa Donckers, to assist her in investigating a serial rapist who has started attacking young women again after a 10-year hiatus. The Professor's encyclopaedic knowledge of criminal psychology and his brilliant mind prove invaluable to the under-resourced CID team, but the cracks in his carefully constructed emotionless carapace also begin to show. This 8-disc collection features every episode of the British remake of the classic Belgian crime procedural series.
