Bradfield must be Britain's most dangerous city -- and every gruesome murder case has now been gathered in one DVD boxset.

And driving each investigation is Robson Green, perfectly cast as the eccentric and hypnotic profiler Tony Hill, one of the best creations of modern crime telly.

He's one of the watchable heroes on telly, up there with House, CSI's Grissom and Lie to Me's Lightman -- and his relationships with the cops Hermione Norris and later Simone Lahbib -- are always interesting.

The new Completely Wired collection offers all their feature-length investigations have of serial killers in full, disturbing, atmospheric, tightly-wound detail.

Sometimes the violence is too voyeuristic, and there are a handful of so-so episodes, but most are very wotchable stories that rank amongst the best of mainstream British crime TV.

With the set, and one sale for the first time separately, is Hill's murder investigation in Texas, Prayer of the Bone, worth watching for fans but not a patch on the main series.

The first two seasons cemented Wire in the Blood as one the most gripping, as well as gruesome, crime series of recent years.

Along with strong stories and atmosphere, what set it apart from other series was the interesting relationship between Robson Green and Hermione Norris.

Simone Lahbib was a worthy successor to Norris, freshening up the series as it settled into plots that -- although still complex and enthralling -- mostly followed a tried-and-tested formula.

While the sixth series was still worth watching, episodes were becoming too predictable and ITV's decision to discontinue was probably the right one.
