In the shadows of Hogwarts, Tom Riddle, in his spectral diary form, became increasingly obsessed with Harry Potter. He had discovered that Harry was using a powerful magical charm, a glamour, to conceal his true appearance and identity. This revelation fueled Tom's determination to unravel the secrets surrounding Harry.

Tom Riddle began to study Harry closely, observing his every move, even though he remained invisible and intangible. He watched as Harry skillfully cast the glamour spell, marveling at the boy's proficiency in magic. It intrigued him that Harry, an ordinary student, possessed such advanced magical abilities.

With each passing day, Tom delved deeper into the mysteries of the glamour. He scrutinized the subtle changes in Harry's appearance and demeanor as he transformed into someone unrecognizable. Tom sought to understand the source of Harry's power and the motivations behind his use of the charm.

As Tom Riddle meticulously observed, he began to piece together clues that suggested Harry was using the glamour not only to protect himself but also to investigate hidden secrets within Hogwarts. This discovery heightened Tom's interest and deepened his obsession with the young wizard.

Tom Riddle's relentless stalking and study of Harry's use of the glamour would set the stage for a dangerous game of cat and mouse. The shadows of Hogwarts held more secrets than even Tom could fathom, and he was determined to exploit every opportunity to further his malevolent agenda.
