Agatha Christie's Partners in Crime (1983)

From the mind of mystery maven Agatha Christie comes what is considered to be the original crime-solving couple, Tommy and Tuppence Beresford. Christie redefined the conventions of the mystery genre with the creation of Tommy and Tuppence, providing a prototype for many male/female detective teams that followed. Set in the 1920s, this popular television series stars James Warwick and Francesca Annis as the eccentric upper-class couple who take over a floundering detective agency and delight in solving any case that comes their way.
