Lester Powell's professional journey began with stints in a curtain shop, on a poultry farm, and in a designer's office, ultimately leading him to a career as a journalist. As World War II unfolded, he served in the Royal Army Medical Corps, arriving in France in the conflict's early months. His military service was marked by a wound sustained during the Battle of Dunkirk in May 1940, after which he returned to England.
Following his military service, Powell worked as a reporter for various newspapers, including the Daily Express and the News Chronicle. During this period, he also contributed to the European and overseas services of the BBC. His broadcasting experience led to a notable creation in 1947: the police radio series starring private detective Philip Odell. The series enjoyed immense popularity, remaining a staple until 1961.
Powell's dedication to his hero, Philip Odell, extended beyond the radio series. He penned five novels and a short story featuring the character, as well as a film adaptation, Lady in the Fog (1952),directed by Sam Newfield for the Hammer studios. The radio drama boasted an impressive cast, with Cesar Romero playing the titular role and Robert Beatty lending his voice to the hero.
In addition to his work on the Philip Odell series, Powell wrote screenplays for various British television series, including Styker of the Yard and Bowler hat and leather boots.
