Query: Painfully slow and boring

The first one hundred pages of this book focused primarily on the protagonist's suspicion that his wife was having an affair. Incredibly, he shrugs off his son's claim that his wife had men in the house while he was at the hospital having his desperately ill child treated for a suspicious illness. The book is unbelievably slow and boring. I gave up after the first one hundred pages. Pass on this one.
