He Is the Fed Lamb

Three people disappeared out of thin air. As a private detective, I noticed one thing in common. They all knew a man named "Bran". Bran is a poor man - in order to save others, he was hit by a train and seriously injured. Now he needs to rely on the care of others to live. Andy, who took care of him, was so gentle that he was almost holy, and so holy that he was almost weird. But my old sergeant friend Hayden rubbed his hands guiltily when talking about Bran's "heroic past". I approached Bran and tried to chat with him. Because of that incident, he suffered from severe sequelae, and there was a possibility of epilepsy when he spoke. It was such a coincidence that he was pretending to be ill when he had an epileptic seizure, but he couldn't be sure. How much does the meticulous Andy beside him know? In those three missing cases where no one was found alive and no body was found, how deep is the shadow hidden behind this seemingly harmless man? (Feeding lamb)
