Over the following few months in the same year, the novel was then republished in several regional British journals. These re-serialisations gave the title as "The Sign of Four". The novel was published in book form in October 1890 by Spencer Blackett, again using the title "The Sign of Four". This edition included a frontispiece illustrated by Charles H. M. Kerr. The title of both the British and American editions of this first book edition omitted the second "the" of the original title.
