Query: 2 and 1/2 stars -- Slooooooow train to nowhere

I've read several of the Burke novels. They have always held my interest -- even when they stretch credulity. This one (NO Burke) is a disappointment. The story starts off OK, but it soon bogs down as the plot widens and widens -- but never thickens. I quit after about 30% of the book. Way too many good books out there waiting for me to stick with this slowpoke.
