What is the author's style in The Final Detail by Harlan Coben?

The language of the novel tends to be comical and attempts to be witty, this is mostly carried out through bad and corny jokes that are told by Myron. At some points however, the book takes on a sad and serious tone. This happens when Myron makes discoveries concerning Clu's death. It also happens when Myron sympathizes over Clu's sordid and marred past. Coben enjoys mixing the two types of language in order to conceive this sort of bipolar tone.
