“I adore them,” she said with a little catch in her voice.
“And they you—with reason!” Poirot bowed again.
A dressing-gong sounded, and we rose to go up to our rooms. At that moment the butler entered with a telegram on a salver which he handed to Lord Yardly. The latter tore it open with a brief word of apology. As he read it he stiffened visibly.
With an ejaculation, he handed it to his wife. Then he glanced at my friend.
“Just a minute, Monsieur Poirot. I feel you ought to know about this. It’s from Hoffberg. He thinks he’s found a customer for the diamond—an American, sailing for the States to-morrow. They’re sending down a chap to-night to vet the stone. By Jove, though, if this goes through——” Words failed him.
Lady Yardly had turned away. She still held the telegram in her hand.
“I wish you wouldn’t sell it, George,” she said, in a low voice. “It’s been in the family so long.” She waited, as though for a reply, but when none came her face hardened. She shrugged her shoulders. “I must go and dress. I suppose I had better display ‘the goods.’” She turned to Poirot with a slight grimace. “It’s one of the most hideous necklaces that was ever designed! George has always promised to have the stones reset for me, but it’s never been done.” She left the room.
Half an hour later, we three were assembled in the great drawing-room awaiting the lady. It was already a few minutes past the dinner hour.
Suddenly there was a low rustle, and Lady Yardly appeared framed in the doorway, a radiant figure in a long white shimmering dress. Round the column of her neck was a rivulet of fire. She stood there with one hand just touching the necklace.
“Behold the sacrifice,” she said gaily. Her ill-humour seemed to have vanished. “Wait while I turn the big light on and you shall feast your eyes on the ugliest necklace in England.”
