So, a rather boring, mild-mannered insurance salesman living in Ohio decides to pay for an experimental blood test from Cambridge that claims to predict future behavior. The results tell him that he's likely to commit murder. You wouldn't expect a comedy with that premise to boast the energy of a mildly edgy family sitcom (the edge: a running theme throughout the book is American hatred) but that seems to have been the plan. It's a decently entertaining, evenly paced, easy, drink-of-water read that's rarely tense or laugh-out-loud funny (that seems to be the publishing sweet spot nowadays) but when the sitcom ending arrives, the moral lands with a total thud, in one fell swoop, completely destroying whatever goodwill you might have earlier been willing to grant. And we're talking the limp kind of goodwill you grant to someone or something whose most sparkling quality is that they're merely inoffensive. Like lightly toasted bread. One star.
