Agatha Christie,
The mystery of the blue train
(1928)
“ They had reached Paris, and the slow journey round the ceinture, with its interminable stops and waits, was very wearisome. When they arrived at the Gare de Lyon she was glad to get out and walk up and down the platform. The keen cold air was refreshing after the steam-heated train. She observed with a smile that her friend of the mink coat was solving the possible awkwardness of the dinner problem in her own way. A dinner basket was being handed up and received through the window by the maid. ”
