Using the provided image of the pet, transform it into a compelling vintage detective character. Depict the pet wearing a classic, patterned tweed deerstalker hat and a small, impeccably tailored trench coat or cape. Position the pet sitting upright at a grand, dark mahogany desk in a richly appointed Victorian study. Beside the pet, place an antique brass-framed magnifying glass and a stack of aged, leather-bound books. The scene should be lit with dramatic, moody lighting, featuring warm, ambient light from a desk lamp or fireplace, creating a classic film noir atmosphere. The composition should be a medium shot, with a slightly low-angle perspective, emphasizing the pet's thoughtful and serious demeanor. Ensure the pet's unique features from the original image are clearly preserved.
