TX:
UK: 26th March, 1969

Notes:
*Featuring John Steed, Tara King, Mother and Rhonda

*The tag scene: When Steed comments about at Rhonda's silence, Mother asks her to say hello to Steed. But the strange voice Steed hears is actually Mother practicing his ventriloquism

*This episode is a reworking of ‘The Great Great Britain Crime’, which was one of three episodes completed by producer John Bryce prior to the return of Brian Clemens and Albert Fennell. They initially thought it was unusable, but the tight production schedule caused them to rethink, and the decision was made to recycle it; they combined footage together with excerpts from ‘The Bird Who Knew Too Much’ (the two opening fight scenes), ‘Murdersville’ and ‘Never, Never Say Die’ (the battle between Steed and Professor Stone) - unfortunately the result is pretty awful…

*For no apparent reason the closing credits begin with the of ‘Izzy Pound and His Incredible Marching Sound’ from ‘The Interrogators’, then segues to a version of the Avengers theme done with piano and orchestra
