London, Vizetelly, 1887. First edition, first impression. Paperback. A good copy. Presumably, given that the present copy is 'the only unabridged edition', the Maxwell edition of the same year must have been published earlier (albeit abridged, presumably). Number 24 in the Sensational Novels series. Some rubbing to the red wrappers and a few short tears and chips, but largely in good condition. Complete in two volumes. Three copies on COPAC, none on the market / sales records. [9228, Hyraxia Books].
