“And now, Hastings,” said Poirot, smiling at me as the door closed behind him. “You see it all, do you not?”

“I don’t know what you mean.”

“Does that list of words tell you nothing?”

I scrutinized it, but was forced to shake my head.

I began work with ‘Bernard’ which might have suggested the local doctor had he come across him at all. Evidently he had not.
