First edition. Not one but two copies, the first in the publisher’s cloth, inscribed to the title page by Sims in the year of publication and the second a very uncommon Victorian paperback issue with illustrated front panel. The first copy is reasonably firmly bound in blue/grey cloth lettered and decorated in red and black, the boards are somewhat bumped, faded and rubbed with minor marking, the text block is toned and dusty with minor spotting. The softcover edition is bound in the original wraps, which are slightly toned and foxed with minor loss to the edges, reasonably well executed repairs to the spine and some staining. The text block is slightly toned, foxed and stained with two small bookplates to the inside front cover. A highly amusing crime caper, or rather a detective caper, the detective being of the amateur and aristocratic variety, with the twist that in physical appearance he greatly resembles the murderer. Sims writing is always entertaining but at crime writing he excelled, unsurprisingly given the interest that he showed in real cases. Most notably the Whitechapel Murders, in which he was an expert and in 1888 he even briefly suspected to be Jack the Ripper himself, perhaps inspiring his use of a similar device in this little novel published shortly afterwards. Uncommon as a first edition in any form, but to find both a cloth and a paperback copy, one being inscribed, is remarkable.
