The Burning Wire

I've read The Burning Wire by Jeffery Deaver which features his very clever quadriplegic detective, Lincoln Rhyme. It galloped along okay with twists and turns as Rhyme and his team investigate who is trying to shut down the New York electricity grid. The "perp" seems very cluey about electricity and the reader learns something as well. He issues demands and when they are not met he murders people using electricity in some truly awful ways. 31/2/5
