The series' original run was immediately preceded by transmission on 9 October 1983 of the same production team's adaptation of Christie's second novel The Secret Adversary, which also starred Annis and Warwick in the same roles and which acted as an introduction for viewers to Agatha Christie's Partners in Crime.
