A woman is badly beaten, and a young lad is arrested on suspicion of dealing, John Boulton is the investigating Officer.
Not a bad episode, it a pretty good story, but I feel this serves primarily to show us just how unscrupulous DS Boulton is, how he's prepared to do anything to get a result, he really does have no morals, unlike Tosh, who stands up to him.
Tom Cotcher definitely doesn't get the best send off here, it's Alan's final episode, and all he does if fuss around with files, and wander around, a shame that his character tailed off towards the end of his time.
This was clearly made a little while before it aired, as Alan's departure was announced some time ago, I was surprised to see him pop up here.
A good Boulton story, 7/10.
