Born in 1890, a native of Providence, Rhode Island, his health was uncertain from childhood and he led a sheltered early life. His semi-invalidism enabled him to read omnivorously, and as a shy imaginative child he began to invent what would in his adult life become a whole macabre fantastic world of his own, peopled by creatures out of his own weird imagination.
As an adult he was retiring, almost a recluse. Tall, thin and pale, but with bright alert eyes, he was much given to wandering his native city in the dark hours of the night, and he became a devoted student of its antiquities.
Although he began to write early he had nothing published until he was in his twenties. He set many of his stories around the imaginary town of Arkham, and invented an entire mythology of his own, its core being the demoniac cult of Cthulhu, based on the lore or legend that the world was at one time inhabited by another race who, in practising black magic, lost their foothold or were expelled, yet live on outside, ever ready to take possession of this earth again.
Since his early death in 1937 his stories have continued to attract attention and praise from an ever-growing audience.
The Rats in the Walls is one of his finest stories. Its tones are dark and chilling and its revelations upsetting and numbing. It is pure Lovecraft.
