Nothing terribly innovative here. Just another interesting detective procedural. The two leads are fun to watch but, surprisingly, lead fairly normal lives. DI Arnold( Scarborough) is struggling with the breakup of his marriage and DI Shamsie (Henry) just had a baby and is making adjustments. But it's all within a normal range and so the emphasis is on the detecting. Their two costars (played by Bankole and Phelps) are a good addition and create a team of uber-competent policepersons. Adrian Scarborough is a revelation. I'm used to seeing him in comic buffoonish roles. He plays it serious here with his cycling, piano playing, dyslexic detective and does it well. The plots are the usual combo of twisty narratives, people lying to the police (sometimes for absurd reasons..."Why didn't I tell you I was at the victim's house five minutes before he was bludgeoned to death? I didn't think it was relevant.") and interrogations accompanied by legal counsel who remain silent and doodle on yellow pads. It's all been done before but it goes down easy. Good show!
