Having boarded a train in France from a helicopter, April Dancer has found a courier when explosives are detonated wrecking the train and the courier, who is also an exotic belly dancer and about to play Mata Hari at a London theatre, dies. April decides to impersonate the dead belly dancer and to prove her credentials is required to demonstrate her abilities to the cast of the play which ends when there is a further murder attempt and then later disappears allowing Slade to chase through London in a left hand drive E Type Jaguar, which he loses when surrounded by a gang of floppy haired hoodlums whom he outwits and reclaims the car.
April meanwhile has been tricked into the backstage area of the theatre becoming locked into a boiler room which then explodes. A masked figure links a statue of the god, Kali (which means death) to the power supply and at the end of her dance Miss Dancer theatrically "dies". However the cable had been found earlier and the team are able to unmask the masked man.
And it's not much of a surprise in who the main bad guy is- it's sort of like a whodunnit set in a theatre. I always found these old theatres, especially backstage, quite spooky. There's some tense moments such as when April Dancer - the ravishing Stefanie Powers- is in the theatre alone and hears Mark's voice- but we know he's too busy racing to the theatre after being held up by some thugs who look like a reject from bubblegum pop band. It's a decent episode, though it lacks that fun charm of The Man from Uncle. Did enjoy it, though.
