Valerie Van Ost in ‘The Avengers’

Dead Man’s Treasure. S6E4 1967

Agent Danvers dies in Steed’s flat before he can give the exact location of a valuable dispatch that he has hidden. The flat is bugged and the avengers are pursued by a number of people taking part in a treasure hunt car rally organized by car-mad George Benstead to find the missing dispatch – the end result being truly shocking in the literal sense.
