Mark Billingham's inscrutable Detective Inspector Tom Thorne was brought to vivid life by David Morrissey in this pair of U.K. telefilms. Two murders, committed mere hours and blocks apart, draw Thorne to the macabre possibility that two serial killers could be working in tandem, in "Scaredy Cat" (2010). Sandra Oh, Aiden Gillen, Eddie Marsan co-star. Then, Thorne learns that a murderer is inducing strokes in his victims─when his latest prey is left alive, but paralyzed─in "Sleepyhead" (2010). Natascha McElhone, Gillen, Marsan co-star. 4 1/2 hrs. total on two discs. Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH).
