Baker has a delicious vocabulary and an obsession for detail that he unleashes in this over-the-top detailed description of one man on his lunch hour. Footnotes abound (they sometimes take up half of the page) creating a structural metaphor for the character's concurrent intellectual, emotional and philosophical contemplations. Validating for anyone who's discovered when asked, "What are you thinking?" that they were thinking of ten or a hundred different things just at that moment.
Baker is an intellectual, but he's no snob. He educates and lifts up his audience while still allowing them room for some silliness, and though his style is rich in detail (in the case of "The Mezzanine" to the point of satire) he leaves room for contemplation. As of this review, I've read four of his books - two non-fiction and two fiction - and the prevailing impression I get is of the author's integrity and passion. I recommend this author and this book.
