A heroine addict taken into Sun Hill tries to ease his trouble by explaining that someone is dealing heroine, by obtaining it legally.
It's a good watch, Andy is an interesting character, his revelation the episode up well. Interesting characters, and a pretty good story, I found it a bit surprising to hear that The NHS dished out heroin, seems hugely unlikely, but I'm very likely wrong. It's a thought provoking watch.
Once again the show deals with someone who is HIV positive, last time round, several years back, it wasn't exactly dealt with in a sensitive manner, here Carver and Pierce treat the potential suspect with the same contempt as everyone else.
Daniel Tobias was very good as Rob Cantley here I thought, a shame I've not seen much of him elsewhere, a very realistic performance here.
8/10.
