Television and screenwriting
A career built in episodes
Horowitz wrote for television before his best-known novels. His credits range from episodes of established drama to series he created himself, giving him long experience with clue placement, act breaks and returning detectives.
Agatha Christie’s Poirot
He adapted multiple Poirot stories for television, working directly with classic detective plotting.
Midsomer Murders
He wrote for the long-running village mystery drama and devised early episodes.
Foyle’s War
Created by Horowitz, the ITV series places detective stories against the social and political detail of wartime Britain.
Collision and Injustice
These authored television serials show his work beyond continuing detective formats.
Susan Ryeland trilogy
Horowitz adapted all three of his nested mysteries for television and served as an executive producer.
This is a documented career overview, with selected credits to help you explore further. The official author guide remains the current source of record.
