The TV programme has a pre-title sequence where an agent, disguised as an old
woman on a bicycle, is shot whilst trying to get away with some photos of the cypher documents. It is
this death that causes Jarret to be sent to investigate Cypher HQ.
The TV show also has the rather visual idea of having Mother direct operations whilst sitting in his
car in the middle of a field. The radio version has him spending most of his time in Steed's flat -
drinking Steed's sherry!
Steed awakens Mrs. Peel in the radio serial by recording a wake-up call over the tape used by the
Classy Glass people to smooth out the Cypher workers' memories. The TV version has Steed using his
pocket-watch chime to wake up Tara.
At the start of Episode Five, Hugh Rouse mistakenly refers to the
character Ferret as 'the Ferret' - this isn't Batman, old chap!
