A trick of the light

James McLevy teams up with Arthur Conan Doyle to pursue a ruthless killer. It is 1860 and a Confederate officer, Jonathen Sinclair, arrives in Edinburgh with a sheaf of money to purchase a blockade-runner from Clydeside shipbuilders. He is betrayed to the Union forces and brutally shot dead by their secret agents. The money vanishes. This incident sets the scene for more foul play in another pacy McLevy thriller.
