The too-serene-to-be-true town of Belleville harbors some creepy secrets in Legrand’s debut, a sinister and occasionally playful tale of suspense. Legrand gives Victoria’s mission a prickly energy, and her descriptions of the sighing, heaving home—a character in itself—are the stuff of bad dreams. Watts’s b&w illustrations of spindly characters, cryptic shadows, and cramped corridors amplify the unsettling ambiance, and her roach motif may have readers checking their arms.
