From France, 19th century X-Files!
From the publisher:
Jean-Baptiste Poulain has been hired by the Baron of Brac to tutor his son. When the young teacher arrives on the island off the coast of Brittany, he's immediately struck by how much the population seems to both hate and fear their lord. Which doesn't stop the locals from going after the aristocrat's people. Jean-Baptiste is brutally attacked just after Nolwenn, the baron's son, is found beaten to death
At the end of the 19th century, Jean-Baptiste Poulain travels to isolated locales, places where ancestral legends & superstitions have surfaced, to investigate and find the truth and to help the populace. Each album of the series constitutes a complete story.
Bonhomme is the artist of Messire Guillaume and Esteban. This was his first BD series and his art and storytelling is lowkey and straightforward like a great 1960s Dell or Gold Key comic.
