The Secret Agent

No book-club edition is documented for 1907. The relevant issue caveat is colonial: of the 2,500 copies, 500 were allotted to Canada and 500 to colonial markets, and Methuen later redirected unsold colonial copies to the home market with no visible evidence of cancellation — colonial and domestic copies are therefore not reliably distinguishable. Copies lacking the 40-page September 1907 advertisement section, or with a corrected p. 117, are later; the Methuen cheap reprints and later collected editions are "first thus" only.
