ANTHONY GEORGE WILLIAMSON

According to Wikipedia: "Tony Williamson (18 December 1932 in Manchester – 19 June 1991) was a prolific British television writer, most active from the mid-1960s to the mid-1980s. He wrote primarily for the action-adventure and espionage genres. Perhaps because of his early involvement in The Avengers, he often found work on shows that featured fantasy adventure, rather than the kitchen sink realism that had arisen in Britain at the start of his career. Series with extraordinary lead characters in unusual circumstances, such as Department S, Jason King, Randall and Hopkirk (Deceased) and The Adventurer, dominated his output."
