Elephants Can Remember (Broché)

Hercule Poirot stood on the clifftop. Here, many years earlier, there had been a tragic accident. This was followed by the grisly discovery of two more bodies - a husband and wife - shot dead. But who had killed whom ? Was it a suicide pact ? A crime of passion ? Or cold-blooded murder ? Poirot delves back into the past and discovers that 'old sins leave long shadows'.
