The Metal Monster (1920) features the return of Dr. Walter T. Goodwin who, after the amazing adventures he had experienced in the South Pacific the previous year, (published in The Moon Pool) had embarked on what he had hoped would be a quiet and healing expedition to study the flora of the Himalayas. There he comes across The Metal Monster.

Mr. A. Merritt is asked to publicize Dr. Goodwin’s report to The International Association of Science in hopes of warning explorers in the wild regions of our planet to be aware of the possibilities of the discoveries of other similar monsters.

This book was a favorite of H. P. Lovecraft. According to his March 6, 1934 letter to James F. Morton:

Other recent items on my calendar are … A. Merritt’s old yarn The Metal Monster, which I had never read before because Eddy told me it was dull. The damn’d fool! (nephew — not our late bibliophilick friend) Actually, the book contains the most remarkable presentation of the utterly alien and non-human that I have ever seen.

Although A. (Abraham) Merritt only wrote eight novels and a handful of short stories in his career, he is considered one of the giants of imaginative fiction.
