Riddle was a model student, a model prefect, and a model housemate. Harry had been watching him for hours and hours each week, and Riddle had yet to slip up. He was perfectly polite to everyone, was in bed by curfew every night, and made absolutely no trouble. Harry even followed Riddle around on evenings and weekends under the invisibility cloak, which had ended up in Harry’s trunk at Hogwarts. Had Henry slipped it in? If he had, Harry was grateful, because it made following Riddle surreptitiously much easier.
