The New York Times Magazine called The Many Aspects of Mobile Home Living "arguably the funniest legal thriller ever written" and declared Martin to be "the thinking man's John Grisham."
The Pittsburgh Tribune-Review called Plain Heathen Mischief "An American fable that combines elements of the archetypal road story with one man's quest for redemption. Martin Clark is a skillful storyteller whose style recalls Thomas McGuane...filtered through a distinctive Southern prism."
Noted southern author Kaye Gibbons had this to say about Many Aspects, "This is a grand, rumbling ride through the world of Evers Wheeling and wild company. Clark's novel is without restraint and perhaps without precedent, unless we consider another man with a mission, Ignatius J. Reilly, juggling a steady job, a perpetual hangover, and a fleet of outstanding weirdos. If I did not live such a sheltered existence, this is the book I'd love to write."
Note: Many locals pronounce heathen with an "r" as in heathren.
