I got no answer, and I turned, a little annoyed. My annoyance was quickly changed to concern. Poirot was lying back across the rude couch, his face horribly convulsed. Beside him was the empty cup. I rushed to his side, then dashed out and across the camp to Dr. Ames’s tent.

“ Dr. Ames!” I cried. “Come at once.”

“What’s the matter?” said the doctor, appearing in pyjamas.

“My friend. He’s ill. Dying. The camomile tea. Don’t let Hassan leave the camp.”

Like a flash the doctor ran to our tent. Poirot was lying as I left him.

“Extraordinary,” cried Ames. “Looks like a seizure⁠—or⁠—what did you say about something he drank?” He picked up the empty cup.
