Avengers: The Quick-Quick-Slow Death on AllMovie

A runaway baby carriage rolls to a halt, revealing that it carries a dead body. Following the trail of clues, Steed and Emma wind up at a dancing school, which is actually the headquarters of an organization that enables enemy spies to infiltrate England. Posing respectively as a potential customer and a dance instructor, Steed and Emma bluff their way into the school -- and of course, nearly end up waltzing into the Next World. Written by Robert Banks Stewart, "Quick-Quick Slow Death" was originally telecast in England on February 5, 1966; though it was not included in ABC's Avengers package, the episode was eventually seen in America via syndication.
