Drenched with suspense
19 February 2011 | by (Youngstown,Ohio) – See all my reviews

The first of five episodes that never aired in the US, "A Surfeit of H2O" is a well remembered entry, in which a level grass field yields its share of victims mysteriously drowned, and the locals believing that another Noah's Ark is necessary to survive the coming flood. Steed gets the best line posing as a wine merchant, choking on a brand described as "old bark," remarking, "they must have put the dog in it too!" Marred only by some intrusive comedy where Jonah Barnard (Noel Purcell) inserts himself into the climactic downpour, this marked the last appearance from Geoffrey Palmer, who had previously done "Dance with Death," "Propellant 23," and "Man with Two Shadows." British actress Sue Lloyd, who played Peter Cushing's demanding wife in 1967's "Corruption," is not to be confused with Canadian actress Suzanne Lloyd (who appeared in the previous episode, "The Murder Market"), John Kidd would return for "Split!", and Talfryn Thomas would return for "Look- (stop me if you've heard this one) But There Were These Two Fellers..."
