Gilbert Keith Chesterton,
The Man Who Was Thursday
(1908)
“ The Doctor's sleek and smiling head did not move, but they could have sworn that under his dark glasses his eyes darted towards Syme. "Dr. Bull," said Syme, in a voice peculiarly precise and courteous, "would you do me a small favour? Would you be so kind as to take off your spectacles?" The Professor swung round on his seat, and stared at Syme with a sort of frozen fury of astonishment. Syme, like a man who has thrown his life and fortune on the table, leaned forward with a fiery face. The Doctor did not move. ”
