The latest work of Dr. Raymond F. Comeau, a Haverhill native and poet, takes readers on a short, distressing and timely trip through the history of cruel oppression and successful resistance. Each reader will identify their own villains and heroes in Comeau’s “Ghouls A-Coming,” but historical candidates include France’s King Louis XVI, who oversaw economic collapse and social upheaval, leading to the French Revolution. The more recent collapse of East Germany after years of citizen abuse by the Stasi secret police may come to mind. Comeau calls out fascists Adolf Hitler and Benito Mussolini by name and worries aloud the ghouls could be released from graveyards. Now of Belmont, Comeau is a retired dean and current lecturer at Harvard University Extension School.
