Query: First of a remarkable series

This book introduces Keith Calder, canny Scottish gunsmith. The complicated and often irrational legal system, which fails to take the realities of Scottish country life into account, forces the local inhabitants to engage in outrageously complicated and frequently technically criminal accommodations. Incompetence and corruption in government and law enforcement compound the problem. Add the occasional murder, and Calder needs all his native shrewdness to find the solutions. This world, at first seemingly exotic, eventually becomes startlingly reminiscent of our own. Although somewhat dated, the books in this entertaining series retain their relevance.
