MacLeish Sq., Dennis Must’s curiously appealing new novel, takes the reader through the obscure final act of a man’s life. The main character, sixty-nine-year-old John Proctor, buys an old farmhouse on the outskirts of the desolate New England mill town he grew up in—the town he left when he was eighteen. Upon returning, John wishes for nothing but to settle “down here outside the derelict mill town of my childhood to savor the days each sunup deigns to grant me.”
