Jason's Grey Cells

In recent years Mr. Morris has turned his attention to prose. He writes regularly for the New York Times’s Opinionator blog, and last year he issued “Believing Is Seeing,” a counterintuitive book of investigative essays about photography. He arrives now with “A Wilderness of Error,” a book about the convicted murderer Jeffrey MacDonald. Bristling with charts, graphs, illustrations, snatches of court transcripts and the author’s own Q. and A.’s with key players, it is the literary equivalent of one of his movies. It’s a rough-hewed documentary master class.
