Trying out the Invisibility Cloak, Harry visits the Restricted Section

After Christmas dinner, Ron immediately falls asleep and Harry decides to use his father’s Invisibility Cloak to explore the castle. Under the cloak, he sneaks past the Fat Lady and then decides to go research Nicolas Flamel in the library’s Restricted Section. The library is very dark and the Restricted Section gives Harry a creepy feeling even after he lights a lamp. Harry hopes to spend as much of the night as is needed to research Flamel, but the first Restricted Section book he tries lets out a loud scream when he opens it. Filch immediately comes to investigate, and Harry narrowly dodges him and runs. Filch reports to Snape that someone was in the Restricted Section.
