The character of Tara King on the television episode is replaced with that
of Emma Peel on the radio.
Mother's lair in the TV version is an empty studio lot with ladders and
coloured telephones scattered around. He also refers to 'Grandma' - his superior.
The television episode features more scenes at Steed's mews flat (probably for time and budgetary
reasons). Steed and Tara meet at the flat to discuss developments, rather than at a restaurant.
Maidwell comes to Steed's flat with examples of his envelopes - we never see the company
In the TV version, Steed hears the sound of typing whilst speaking to Matron for the first time. He
does return later that night to search her office but only finds the directories and Timothy's
letter - we do not see the room full of typists.
The radio version makes no mention of a large model nose on the wall in Timothy's clinic. This
is important in the TV episode as it has ladders inside the nostrils, leading from the air
shafts, and it is down one of these that Tara falls when she sneezes, and also whilst climbing
down one of the ladders that Glover is showered with cold virus powder by Steed.
The TV version of the cells are also individual deep freeze rooms, so Tara is not moved to another
room when Matron tries to cool her down. Tara is also consciously looks into the sacks of envelopes,
rather than falling on them.
The TV Steed comments that the Colonel's clinic is "Not to be sneezed at!" at one point, but unlike
his radio counterpart, does not claim to speak Swahili.
The offices of Padley, Seaton and Herrick do not appear to be near a park in the TV version, and
Herrick's car crashes into a wall rather than a tree.
In the television Allergy Laboratory Preece, Matron and Dexter all assist in filling the envelopes.
Tara is later tied up there by both arms from a metal beam.
For this story, regular "Mother" Colin Fish
was not available, and was replaced by Anthony Fridjhon.
