They're mad for the mystery dramas over at the BBC these days. Sure didn't we spend a spooky five days with the Mayday crew last week and all? Anyway, tonight we're getting the first of a two part murder mystery, set on the Shetland Islands. No kidding. Drama veteran Douglas Henshall leads the cast as Detective Jimmy Perez, a native of the islands who returns home to figure out the truth about a set of human remains, found during an archaeological dig. Are talking about a whole lotta history? Or is modern day murder on the cards? Concludes tomorrow night.
