These are three excellent extended stories (each over 2 hours) and set the high standard of the series for involved plots, `red herrings' and for the acting and production. The idea was conceived by Glenn Chandler, and Mark McManus played the cynical and disillusioned Glasgow detective, Jim Taggart, so very well. The first episode, `Killer', was aired in 1983. These three DVDs must have been amongst the early episodes of the series, possibly all from 1986 or 1987 when the character of Michael Jardine was introduced. McManus was ably supported from the first episodes by Harriet Buchan as his long-suffering disabled wife Jean. The 3 DVDs here are for the stories `Knife edge'. Flesh & blood', and `Nest of vipers'. Inevitably they don't move with the pace of some modern detective stories, but are highly entertaining nonetheless.
