After Mary has gone Poirot goes out and Hastings receives a visit from Lady Yardly, who was advised to visit Poirot by her friend Mary Cavendish. The Yardlys also own an identical diamond that came from the right eye of the idol – the Star of the East.

Her husband, Gregory Rolf, who bought it from a Chinese man in San Francisco, gave Mary the jewel three years ago. She has received three letters, handed to her by a Chinese man, which warn her to return her fabulous diamond jewel, the 'Western Star', to where it came from – the left eye of an idol – before the next full moon.
