'You have been to the Riviera before, Georges?' said Poirot to his valet the following morning. George was an intensely English, rather wooden-faced individual.'Yes, sir. I was here two years ago when I was in the service of Lord Edward Frampton.''And today,' murmured his master, 'you are here with Hercule Poirot. How one mounts in the world!'The valet made no reply to this observation. After a suitable pause he asked:'The brown lounge suit, sir? The wind is somewhat chilly today.''There is a grease spot on the waistcoat,' objected Poirot. 'A morceau of Fillet de sole à la Jeanette alighted there when I was lunching at the Ritz last Tuesday.''There is no spot there now, sir,' said George reproachfully. 'I have removed it.''Très bien!' said Poirot. 'I am pleased with you, Georges.''Thank you, sir.'
The Mystery of the Blue Train (1928)
This book offers one of my favourite clichés.
Tommy also eats sole à la Jeanette in The Secret Adversary.
Was it a Christie invention?
