The Lair of the White Worm

UK Rider 1911 is the true first and the only first — there was no simultaneous or near-simultaneous American edition. The novel was not published in the United States until 1966, when Paperback Library (New York) issued it in its Gothic series retitled The Garden of Evil, a mass-market paperback with cover art by Victor Kalin. That is the first American appearance, but it is a paperback reprint of a 55-year-old text and not a first edition in any collecting sense. Only the Rider 1911 is collected as the first.
