* K is for Kill parts 1 and 2 were apparently combined into a long-form special for the American market.

Episodes are listed in order of first transmission to the Greater London area, but are numbered according to Dave Rogers' books (the order of the last four episodes in Season One and a bit of rearrangement of the latter part of Season Two are the only differences).
Also indicated is the production order of the episodes and a choice of regional and international transmission dates (Sydney, Melbourne, Paris and New York City). - I've chosen to list Wales (HTV) as it was frequently the first station to broadcast the episodes.
