This is a compilation of four short stories spanning - in real time - all is explained in the book- the history of Dalziel and Pascoe. It is witty, clever, tightly plotted and reveals parts of Andy Dalziels life only previously hinted at! It is throughly readable but not if this your first venture into D&P territory. It has more humour in it than the usual D&P. Written for regular readers it contains "in jokes" and references. Ultimatly it fills in the background, fleshes out the characters and is wholly enjoyable
