Sam Pulsifer can't extinguish his burning desires

The narrator of An Arsonist's Guide to Writers' Homes in New England is an accidental firebug "with blood and soot on his hands."

He committed the unspeakable crime of burning down Emily Dickinson's house. Thus, he threw Amherst, Massachusetts, into turmoil, not only because he violated the legacy of the college town's cherished literary Belle but also because he killed "two of its loafered citizens" in the process.

His name, Sam Pulsifer, is redolent of both pusillanimity and Lucifer. But the actual Sam is too mousy and naive for either. He would have fared better in life had he been less dimwitted, "like a child, only bigger" in the opinion of one of his smarter acquaintances. But he wouldn't have been as wildly, unpredictably funny. And the hilarity of Sam's narrative voice is fine compensation for its apparent idiocy.

An Arsonist's Guide to Writers' Homes in New England is as cheerfully oddball as its title. Its cover art includes a tiny cartoon sketch of a green-frocked literary lioness garlanded in flames, and that captures the irreverence of the author, Brock Clarke's, enterprise. Although it is his fourth book, it feels like the bright debut of an ingeniously arch humorist, one whose hallmark is a calm approach to insanely improbable behavior.

"I could think of no bigger betrayal than a wife's changing the locks on her husband," thinks an aggrieved Sam, "just as long as I didn't think about my burning and killing and then lying about it."

Clarke's premise gives him an immediate problem to solve. If Sam really torched a treasured landmark and killed people, then served 10 years in prison by the time this story begins, what kind of monster is he? In order to treat this character as a lovable marshmallow, as well as an occasionally inspired literary satirist, Clarke must figure out how to sustain this novel's sunny atmosphere without having to justify heinous violence.

So it gradually develops that Sam didn't exactly mean to incinerate anything or hurt anyone. It happened to him as accidentally as everything else in his life occurs, amid the cloud of bewilderment that follows him everywhere.

Sam never meant to become a serial arsonist. It's just that the Dickinson fire brought forth a barrage of strange correspondence. Sam predictably prompted the rage of scholars, even if their fury failed to impress him. "There is something underwhelming," he writes, " about scholarly hate mail - the sad literary allusions, the refusal to use contractions - so I didn't pay much attention to those letters at all." But Sam also got dozens of letters from angry lunatics requesting that he burn down more writers' homes.

Here too Clarke must be careful. His book's craziness must stay jokey. It gets no crazier than the man who wants Ralph Waldo Emerson's house destroyed to avenge his parents' naming him Waldo. So Sam has no plans to fulfill his fans' requests. He prefers a safer course. After prison he went to college to major in packaging science, which comes in handy whenever he wants to use a Ziploc bag or a mayonnaise jar as a metaphor during this narrative.

He met a woman named Anne Marie. He invited her to have dinner. ("'With you?' she asked.") Then he married her and took up the life of a suburban father. As the book begins, he lives on Hyannisport Drive in a subdivision called Camelot, a place so quiet on weekdays that "you couldn't clip your toenails on your front porch without fear of bothering someone with the noise." Sam accurately surmises that despite Camelot's proximity to Amherst, the two are worlds apart, and nobody cares about Emily Dickinson in a place like this.
