Elsewhere, the morbid business of investigating corpses and crime scenes is enlivened with flashes of welcome humour: when a horse is found dead with packets of uncut diamonds concealed in its uterus, Grissom deadpans "This horse is a mule". Throughout, the show remains focused on its scientific remit, only revealing enough of the characters' private lives to provide added piquancy to each investigation: Sarah's complete lack of a life outside her work; Warrick's old gambling habit; Catherine's attachment to her daughter and troubles with ex-husband Eddie; Nick's over-eagerness to please. Grissom, meanwhile, like the Dalai Lama, is the model of inscrutable wisdom. The show itself, like a millennial antidote to a decade of X-Files, is relentlessly empirical: everything that initially seems mysterious--from spontaneous human combustion to an apparent case of vampirism--is always explicable and explained by the team's scientific dedication.

On the DVD: CSI, Series 1 Part 2 contains 11 episodes on three discs. Extra features consist of a brief promo featurette, production notes and a series of on-set interviews with the cast. Oddly for such a cutting-edge show, picture is old-fashioned 4:3 with basic Dolby stereo sound. --Mark Walker
