Coronation Street's 15th anniversary was marked by an ambitious storyline in which the Mark Brittain Warehouse was accidentally set alight, starting an inferno which claimed the life of Edna Gee and caused the Street to be evacuated. Episode 1536, set in the aftermath of the fire, was the first script written by Tony Warren since 1969. The storyline saw the first fleeting appearance of Edna's husband Fred, played by Fred Feast, who would return full-time the following year. The warehouse was subsequently closed permanently.
