Callan Season 2 Episode 14 Nice People Die at Home

A father and daughter by the name of Marshall are Soviet agents whose cover is a pet shop in Shepherds Bush, London. They are petty agents, very small fry indeed, and the father is very ill with only a couple of months to live. The daughter wants to take him back to Austria before he dies.

Callan is sent to them impersonating a Soviet agent named Ross who has just arrived in London, an agent who specialises in microdots. Callan is hoping that the Marshalls will be able to lead him to top Soviet agent Belukov.

Hunter wants Belukov and the Marshalls eliminated, but Callan feels that the Marshalls are innocents who need a break. During a fight Belukov is wounded by Nadia Marshall. Callan takes Belukov to a hideout and contacts Hunter. He tells Hunter that unless the Marshalls are allowed onto a plane to Austria he will release Belukov to the Russian Embassy.
