The episode:  'Death from a Distance' was the ninth episode of the first season, and was broadcast on 4 November 1961.
Sir Andrew Wilson sends Nick Craig on two weeks' vacation and temporarily transfers Stephen Brett from Scotland Yard to
the Ghost Squad for "special duties", as a new case needs a man with international experience.  London is to be the venue
for a meeting of European heads of state, which will attended by Volgu (John Le Mesurier), the ruler of a Balkans nation who
made many enemies when he seized power. The Ghost Squad is aware that there are four men in London who want to kill
Volgu.  Sir Andrew arranges for the four men to be lured out of London for the duration of the meeting, using one of Volgu's
greatest enemies as bait. They are invited to this man's home in the New Hebrides, but Sir Andrew organises for their plane
to be diverted to a small island where they are left stranded. The four men include Router (Anton Diffring), a biochemist who
blames Volgu for the death of his 15-year-old son, and Holgar (Roger Delgado), who used to be rich but now must work as
a waiter. The four men escape from the island in a small boat, but Holgar dies on the journey, due to a bad heart (courtesy
of Volgu), and Router proceeds to London where he plans to kill Volgu using poisoned flowers that are to be presented to
him by Router's niece. Brett foils the plot at the last minute. Diffring later played played De Flores in Silver Nemesis.
