The Professor Challenger Collection

The Professor Challenger Collection includes the two most important full-length novels featuring Professor Challenger.

George Edward Challenger is a fictional character in a series of fantasy and science fiction stories by Sir Arthur Conan Doyle. Unlike Conan Doyle's self-controlled, analytical character, Sherlock Holmes, Professor Challenger is an aggressive, hot-tempered, dominating figure. Like Sherlock Holmes, Professor Challenger was based on real persons - in this case, an explorer named Percy Fawcett, who was Conan Doyle's friend, and a professor of physiology named William Rutherford, who had lectured at the University of Edinburgh while Conan Doyle studied medicine there.

The Lost World is a science fiction novel by British writer Arthur Conan Doyle, published in 1912, concerning an expedition to a plateau in the Amazon basin of South America where prehistoric animals still survive. It was originally published serially in the Strand Magazine and illustrated by New-Zealand-born artist Harry Rountree during the months of April-November 1912. The character of Professor Challenger was introduced in this book. The novel also describes a war between indigenous people and a vicious tribe of ape-like creatures.

The Poison Belt is a science fiction novel by British writer Arthur Conan Doyle, the second book about Professor Challenger. Written in 1913, much of it takes place in a single room in Challenger's house in Sussex. This would be the last story written about Challenger until the 1920s, by which time Doyle's spiritualist beliefs had begun to influence his writing.
