Final answer:
Walter Gripp is depicted as a person with a blend of cleverness and gullibility, deeply enthralled by tales of the supernatural, giving him a haunting presence.
Step-by-step explanation:
According to December 2005: The Silent Towns, Walter Gripp can be characterized as a mix of cunning and naivety. His love for the extraordinary is as pronounced as his ability to believe in incredible stories, having been heightened by the magical surroundings he resides in. His evenings are often spent absorbed in the tales of the supernatural until the fall of night enhances the atmosphere of his eerie journey home. Gripp's defense against the unknown is to sing psalm tunes which resonate with the people of Sleepy Hollow and heighten the mystique of his character.
