Before we get back to our current Wednesday series on bishop’s palaces, we pause to remember the death of celebrated crime writer Agatha Christie, 50 years ago this week (she died on 12th January, 1976).

• First up, we head to 58 Sheffield Terrace in Holland Park where Christie lived with her second husband, archaeologist Max Mallowan, between 1934 and 1941 (one of several homes she lived in in the area), and where she wrote books including Murder on the Orient Express (1934) and Death on the Nile (1937). The house is marked with an English Heritage Blue Plaque.

• Then it’s over to University College Hospital in Bloomsbury where Christie worked during World War II as a volunteer dispenser (and where she added to her expertise on poisons). Christie had in 1917 sat three exams to become a qualified pharmaceutical assistant at the Apothecaries Hall in London.

• Finally, we head to the West End and St Martin’s Theatre where Christie’s play, The Mousetrap, continues to be performed nightly, notching up more than 30,000 performances. Outside is the Agatha Christie Memorial (pictured) depicting a book with a bust of Christie set into the centre.

We’ll be taking a more detailed look at Agatha Christie’s London in a series soon…
