Trial by Fury — Craig Rice

The first victim was shot in the back. The second victim was blown to bits. The third victim was strangled. The fourth victim was knifed.

For each death a different method. And while frantic police made all the wrong guesses, and a town that had become a slaughterhouse went wild with fear, a four-time killer plotted his fifth murder. This time, he would use the most hideous weapon of all.
