London, W. Collins, 1927. First UK edition. Heberdon's hobby was crime, but he crossed the line in order to prove his assertion that a reasonably bright crook would undertake no greater risk than someone in an honest line of work. Corners bumped with wear to extremities. Spotting to boards, bookplate to front endpaper. Part of rear endpaper missing, neatly cut in two. $25.00.
