8vo. viii, iii-vi, 5-434pp. Initial 'Address' bound out of order, but complete. With an engraved frontispiece and seven further engraved plates, five of which bear portraits of the conspirators. Modern navy morocco-backed marbled boards, thematic devices stamped in gilt to spine, with contrasting gilt-tooled black morocco lettering-piece. A trifle rubbed. Leaves lightly browned, with tape repair to first blank fly-leaf, scattered spotting, and light marking throughout.

The first edition of the first thorough account of the Cato Street conspiracy, a plot to assassinate the prime minister and his cabinet, and to install a new revolutionary government. Written by the editor of the New Newgate Calendar Improved, the reports follow the sensationalised approach to crime reporting of that publication, detailing the plot, the involvement of a police spy (who is described, despite the general tone of disapproval for the conspirators, as ‘that base and infamous individual George Edwards, the spy and instigator to treason’), the conspirators’ trials and execution, and the backgrounds and characters of the conspirators.
