It's another of those attempts to fill the post XFiles sci-fi mystery void, but it met with general apathy in the US and was whipped off the air after six episodes in 2005. There were actually ten filmed in total (the unbroadcast ones appearing online as downloads) though whether Virgin Media will make all ten available I don't know. Here's a summary from tv.com:
Crime reporter Carl Kolchak is partnered with Perri Reed at The Beacon , a Los Angeles newspaper. Together they investigate a string of strange murders...all of which may be related to the death of Kolchak's wife 18 months earlier in a similarly bizarre manner.
Be warned: the tenth episode ends with an unresolved cliffhanger.
(Incidentally, Lord of the Rings fans may find leading man Stuart Townsend interesting to watch; he was Peter Jackson's original choice for Aragorn, but was sacked after a few days of filming as it was felt he was too young for the role.)
