Dracula
by
Bram Stoker
Meanwhile, in the broad and lofty chamber set apart for occasions of import, the Abbot himself was pacing impatiently backwards and forwards, with his long white nervous hands clasped in front of him. His thin, thought-worn features and sunken, haggard cheeks bespoke one who had indeed beaten down that inner foe whom every man must face, but had none the less suffered sorely in the contest. In crushing his passions he had well-nigh crushed himself.
