The Sound of His Horn is a 1952 dystopian time travel/alternative history novel by the senior British diplomat John William Wall, written under the pseudonym Sarban.

Querdillon manages to escape the doctor and join the Count's entourage to witness genetically modified leopard-women attacking deer.

In his introduction to the 1960 edition of the novel by Ballantine Books, Kingsley Amis wrote, "I shall always feel a slight twinge whenever I am reminded of the innocent English hunting song from which the title is taken".

Writing for The Magazine of Fantasy & Science Fiction, author Damon Knight commented that the book was "a minor thing, crude in places, but persuasive.

"[1] Thomas M. Disch ranked The Sound of His Horn at number twelve in his list of the all-time greatest fantasy stories.
