Query: Disappointing

I'm a long-standing Ludlum fan who took a break several years ago, disappointed by the Road to Gandolfo. I decided to sample his work again. It's a quick read, but quite disappointing. The central figure is a pale imitation of Jason Bourne who, in this work, tangles with the evil incarnation of a powerful executive of a far-reaching corporation based in the Pacific Northwest (get the picture, Bill?).Think I'll take a break for a few more years.
