“And lastly — I hope you are not too sleepy to pay attention to this, Harry — the young Tom Riddle liked to collect trophies. You saw the box of stolen articles he had hidden in his room.

Bear in mind this magpie-like tendency, for this, particularly, will be important later”
― J.K. Rowling, Harry Potter and the Half-Blood Prince
