“I had it from a friend of mine,” said Mr. Aarons. “But for all I know, it may be coloured glass. They are all the same, these women⁠—they never stop telling tall stories about their jewels. Mirelle goes about bragging that it has got a curse on it. ‘Heart of Fire,’ I think she calls it.”

“But if I remember rightly,” said Poirot, “the ruby that is named ‘Heart of Fire’ is the centre stone in a necklace.”

“There you are! Didn’t I tell you there is no end to the lies women will tell about their jewellery? This is a single stone, hung on a platinum chain round her neck; but, as I said before, ten to one it is a bit of coloured glass.”

“No,” said Poirot gently; “no⁠—somehow I do not think it is coloured glass.”
