The Purple Cloud is an apocalyptic "last man" novel by the British writer M. P. Shiel. It was published in 1901. H. G. Wells lauded The Purple Cloud as "brilliant" and H. P. Lovecraft later praised the novel as exemplary weird fiction, "delivered with a skill and artistry falling little short of actual majesty."
Matthew Phipps Shiell (21 July 1865 – 17 February 1947), known as M. P. Shiel, was a British writer. His legal surname remained "Shiell" though he adopted the shorter version as a de facto pen name.
He is remembered mainly for supernatural horror and scientific romances. His work was published as serials, novels, and as short stories. The Purple Cloud (1901, revised 1929) remains his most often reprinted novel.
