Издание полностью на английском языке.
Hercule Poirot stood on the cliff-top. Here, many years earlier, there had been a fatal accident. This was followed by the grisly discovery of two 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".
