Fehr, a one-time top agent and colleague of Steed's, is knocked
unconscious in a road accident whilst in charge of a pram - a pram which
contains the body of a dead man in full evening dress. Fehr seems
unwilling or unable to say what has happened, so the only lead is a tattoo
on the dead man's arm. Mrs. Peel discovers that the tattoo identifies the
body as one Arthur Peever, and this is confirmed when Steed checks on the
hired suit the dead man was wearing. It becomes clear that the two agents
are on the right track when both the assistant at the suit hire shop, and
the tattooist are both murdered. However, the tattoo artist leaves a clue
to his killer - the assassin has a rose tattoo on his wrist.
...is for Mrs. Peel's feet. Well, it
takes all sorts, doesn't it?
clue turns out to be the corpse's shoes - pumps supplied for students at a
dancing school, Terpsichorean Training Techniques (which also explains the
evening suit). Mrs. Peel joins the school as an instructress, where she
discovers that one of the pupils is 'Arthur Peever', who seems alive and
well - although he does not resemble the corpse Fehr was ferrying at all.
The dance school is run by Lucille Banks with a chief instructor by the
name of Ivor Bracewell, and the drunken school band leader - Chester Read.
Steed also helps out with the investigation by enrolling as a student at
the school. He notices how Miss Banks becomes interested at his interview,
when he mentions that he has been out of the country for some time, and
has no close friends or relatives.
that 'Peever' is an imposter, Mrs. Peel goes to see Bernard, a craftsman
at the shoe shop in the hope that he might have information about the
dance students - Bernard has been supplying cut-price dancing shoes to the
TTT pupils. However, Bernard has been suffocated by being knocked
unconscious and having his face pressed into a bowl of drying plaster. So
Mrs. Peel returns to the school to snoop on Lucille and company. She sees
Lucille dancing with a dummy, which is then swapped for a man when Lucille
passes out of sight in the ballroom. Emma reports what she's seen to
Steed, when they meet at the dance Gala. They realise that this is the
method by which people disappear and are replaced with incoming foreign
agents who take on the missing person's identity. They know that the next
victim will be wearing number 9 on his back at the Gala, and when Steed is
given the number 6, they think he is not the victim. But Lucille cunningly
upturns his number to read '9' and Mrs. Peel realises Steed is in danger.
Steed and Lucille dance away, Mrs. Peel and her partner follow. She
manages to warn Steed and together they overpower their partners - Lucille
and Bracewell. Peever also attacks but is knocked out. However, Chester
Read comes after them with a gun and reveals himself as the ringleader of
the operation - but he too is despatched. Steed and Mrs. Peel dance on
into the night.
