The Deadly Assassin (1976) is a pivotal Doctor Who
story, reimagining the Time Lords and established much of the
continuity and iconography still used today. Arguably the defining
script of Robert Holmes’ prolific career, it showcases his gifts for
worldbuilding, linguistic inventiveness and social satire. Though firmly
grounded in 1970s politics, it also draws on older roots in Gothic
fiction, film noir and Holmes’ experience of the Second World War.
