Find the name of a master of western horror novels

She had read his collection of novels about ten years ago. At that time, she was still young and didn't know how to remember the author's name. Recently, she had been thinking about this collection of novels, but she couldn't find it anymore. The protagonist of the novel was an eleven or twelve-year-old boy. He had a pet that was a crow that he picked up in the snow. The crow was psychic. The protagonist had two companions, a pair of siblings. The elder sister was the same age as the protagonist, and the younger brother was eight or nine years old. The story in the novel collection was roughly set in the 1980s and 1990s. According to my memory, the location should be England. Every story in the novel is about a variety of things. There are black cats and witches, the number 13 and knights, tropical creatures, and visitors from hell. That was all she remembered.
