But did every one suspect him? What about Mrs. Cavendish? I
watched her as she sat at the head of the table, graceful,
composed, enigmatic. In her soft grey frock, with white ruffles
at the wrists falling over her slender hands, she looked very
beautiful. When she chose, however, her face could be
sphinx-like in its inscrutability. She was very silent, hardly
opening her lips, and yet in some queer way I felt that the great
strength of her personality was dominating us all.

And little Cynthia? Did she suspect? She looked very tired and
ill, I thought. The heaviness and languor of her manner were
very marked. I asked her if she were feeling ill, and she
answered frankly:

"Yes, I've got the most beastly headache."

"Have another cup of coffee, mademoiselle?" said Poirot
solicitously. "It will revive you. It is unparalleled for the
mal de tete." He jumped up and took her cup.

"No sugar," said Cynthia, watching him, as he picked up the
sugar-tongs.

"No sugar? You abandon it in the war-time, eh?"

"No, I never take it in coffee."

"Sacre!" murmured Poirot to himself, as he brought back the
replenished cup.
