During this singular conversation Steinfeld had sat, leaning back in his large elbow-chair, in an attitude of easy indifference--one slippered foot thrown carelessly over the other, and his hands thrust into the pockets of his damask dressing-gown. On receiving this last outrageous insult, his lip blanched with passion, his whole person quivered as with an electric shock, and he half rose from his semi-recumbent position. But the baron was a man of vast self-command; one of those cool-headed cool-hearted egotists who rarely act upon impulse, or compromise their interests by ill-timed impetuosity. The first choleric movement, prompting him to throw Fatello downstairs, was checked with wonderful promptitude, and with little appearance of effort.

Fatello, his violence checked for the moment from further outbreak by the baron's courtesy and coolness, made a gesture of sullen assent. "And that you overheard a part, but not the whole, of my conversation with the black domino in question?" "I heard enough, and too much," replied Fatello, with a savage scowl at his interlocutor. "This is idle talk, mere gain of time. Baron Steinfeld!" cried the banker, in a voice that again rose high above its usual pitch, "you are----"
