Arthur Conan Doyle,
The Pot of Caviare
(1908)
“ Pretty Jessie Patterson's bright face shone with her sunny, boyish smile."Why, how earnest you are!" she laughed. "I had no idea you were so polite, Professor Mercer. Even if I do not eat it I am just as grateful.""You are foolish not to eat it," said the Professor, with such intensity that the smile died from her face and her eyes reflected the earnestness of his own. "I tell you it is foolish not to eat caviare to-night." ”
