synopsis
A sneezing epidemic claims the lives of several prominent ear-nose-throat specialists. The only clue tying the deaths together is an empty envelope, found at the scene of each tragedy. Steed and Tara manage to trace this slim lead to a sinister nursing school. Written by Jeremy Burnham (a frequent guest actor on the series), "You'll Catch Your Death" was first shown in America on October 7, 1968, and was seen in England on October 16; the episode is also known as "Atishoo, Atishoo, All Fall Down."
