The second series opens with two new Sandbaggers: Tom Elliott (David Beames), who is soon killed, and Mike Wallace (Michael Cashman), who survives as Sandbagger Two as of the end of the third series. Another recurring character is Edward Tyler (Peter Laird), the SIS Director of Intelligence (D-Int), introduced in the first episode of the second series. Tyler and Burnside share a friendly relationship, but Tyler dies early in the third series and is replaced by Paul Dalgetty (David Robb). Dalgetty, who appears in only two episodes, is openly antagonistic towards Burnside and is briefly scheduled to replace Burnside as D-Ops, owing to a KGB plot in "Who Needs Enemies" (S03E06).
