Short Review: I am a fan of Keith Thomson because of his Once/Twice a Spy novels. Seven Grams of Lead is less funny, more traditional spy thriller and has more action. In fact the action is basically non-stop from start to finish. Part of what I like about many spy novels is the slow build and relatively slowness. It is not that this is a bad book, I enjoyed it mostly. But I think it depended too much on action.
