Forgettable performance by the main characters of a London crime unit in the investigation of two serial killer cases; plots, hats off to the writer Mark Billingham, were complex and wonderful but often mangled in a choppy pace with one too many tired social drama or work place politics. Thorne came across as an insensitive self-centered bully in the first case and a sophomoric know-it-all copper in the second. No wonder it got only 1.5% viewer share per Wikipedia:
"Running on a Sunday evening in the prime 2100 slot on satellite against strong terrestrial competition from the popular Julian Fellowes' period drama series Downton Abbey, the first episode of four-part drama Single Father starring David Tennant, and a reshowing of the Dan Brown thriller The Da Vinci Code, the show drew 402,000 viewers and 1.5% audience share, according to preliminary BARB figures."
