Los elefantes pueden recordar

Blurb

Elephants Can Remember is a work of detective fiction by Agatha Christie, first published in the UK by the Collins Crime Club in November 1972 and in the US by Dodd, Mead and Company later in the same year. The UK edition retailed for £1.60 and the US edition at $6.95.
It features her Belgian detective Hercule Poirot and the recurring character Ariadne Oliver. This was the last Christie's novel to feature either character, although in terms of publication it was succeeded by Curtain: Poirot's Last Case, which had been written in the early 1940s but published last. The novel is notable for its concentration on memory and oral testimony.
