Dark Spectre

What is it that binds together a series of violent murders across America and the long-lost Secret of the Templars?   The killings always take place in the home, usually in broad daylight, in towns and cities all over America. The victims are of every age and background; they have been bound and gagged and shot in the head at close range. The crimes appear to be random and motiveless and no one has claimed responsibility.   So what connects the killings to an obscure religious sect operating from an island in the Pacific North-West? And what clues lie hidden in the Secret of the Templars?   If you enjoyed Dark Spectre you may also like Dirty Tricks, also by Michael Dibdin.
