LONDON.- The Agatha Christie: Unfinished Portrait photography exhibition offers a new insight into the life of Agatha Christie and opened at Bankside Gallery in London this summer, as part of the 125th anniversary celebrations of the Queen of Crime.

Featuring never before seen photographs from the author's private collection, the exhibition illustrates the life behind the works of the most widely published author of all time.

Each image is accompanied by a quote in Christie's own words, drawn from both published works and unpublished personal correspondence, beautifully capturing her thoughts and feelings from early childhood, through both marriages and her international adventures, to her years as a world famous author.

A timeline sits alongside the pictures and mark the key milestones in Christie's life. The jewel in the crown of the exhibition is a portrait of Agatha Christie by expressionist painter Oscar Kokoschka, painted in 1969 for Christie's 80th birthday.

After their London debut, the photographs will tour, appearing first at Torre Abbey in Torquay as part of the International Agatha Christie Festival from 11th-20th September, and then will be in display at Torre Abbey until the 18th October 2015.
