An honest policeman, Sergeant Wigan, escorts a drunk man home one night to keep him out of trouble and, seeing his fine book collection, slowly falls in to the gentle art of book collecting. Just as the friendship is blossoming, the policeman's book-collecting friend is murdered. To solve the mystery of why the victim was killed, and which of his rare books was taken, Wigan dives into the world of 'runners' and book collectors, where avid agents will gladly cut you for a first edition and then offer you a lift home afterwards. This adventurous mystery, which combines exuberant characters with a wonderfully realised depiction of the second-hand book market, is sure to delight bibliophiles and classic crime enthusiasts alike.
