Elephants can remember

Elephants Can Remember is a work of detective fiction by British writer Agatha Christie, first published in 1972. It features her Belgian detective Hercule Poirot and the recurring character Ariadne Oliver. This was the last novel to feature either character, although it was succeeded by Curtain: Poirot's Last Case, which had been written in the early 1940s but was published last. Elephants Can Remember concentrates on memory and oral testimony.
