Garu-chan stood in front of a high-end jewelry store in the bustling streets of the port town. A large billboard in front of the store featured a beautiful ring. At that moment, the store owner rushed out. 'Garu-chan Detective, please help! A valuable ring that was stored in the shop has disappeared!' Garu-chan entered the store with her child on her back and began searching for clues. Although the store was not in disarray, Garu-chan's sensitive nose picked up the scent of the person who last saw the ring. Garu-chan used her reasoning to get closer to the truth. She realized that the relationship between the store owner's wife and one of the store's employees held the key to the case. Garu-chan started questioning the store owner's wife to reveal the facts. Did you hide the ring, or is someone else involved? Garu-chan's question caught the store owner's wife off guard, and she showed a surprised expression.
