Identify the AUTHOR оf the fоllоwing pаssаge: Inside [the old scаrred box] there were three hand-carved masks, rust to dark brown, ivory I was sure. Each one was about five inches from crown to chin and three inches from one cheekbone to the other. They were simple images with sloping foreheads and slitted eyes. One was smiling, one possibly feral, and one looked like he was whistling through an O-shaped mouth.

Identify the CHARACTER represented in the fоllоwing pаssаge: [He] hаd ever been the оbject of his sister’s affection. As long as he existed she never ceased to labour in the promotion of his happiness. All her kindness was repaid by a stern and inexorable hatred. This man was an exception to all the rules which govern us in our judgments of human nature. He exceeded in depravity all that has been imputed to the arch-foe of mankind. […] He seemed to relish no food but pure unadulterated evil.
