Partners in Crime (UK TV series) commissioned by Ben Stephenson and Charlotte Moore for the BBC to mark the 125th anniversary of Agatha Christie's birth. The adaptation was produced by Endor Productions in partnership with Agatha Christie Productions. David Walliams and Hilary Strong (Agatha Christie Group) approached Hilary Bevan Jones and Tom Nash (development producer) of Endor Productions with the idea of re-inventing the Agatha Christie characters Tommy and Tuppence Beresford. Walliams liked the idea of a married amateur detective duo bickering over a dead body. Agatha Christie wrote stories featuring the Beresfords between 1922 and 1973, depicting Tommy and Tuppence from before they were married
Partners in Crime (short story collection) can take on cases as this detective agency, an opportunity that delights the young couple. They employ Albert, a young man also introduced in "The Secret Adversary", as their assistant at the agency. The two tackle a series of cases – mimicking in each the style of a famous fictional detective of the period, including Sherlock Holmes and Christie's own Hercule Poirot. At the end of the book, Tuppence reveals that she is pregnant, and will play a diminished role in the spy business. Prudence ("Tuppence") Beresford, who is happily married to Tommy for six years, is bored with life.
