Autor's note: I apologise for taking this long to update. Will try to be more regular from now on. This one is a short chapter without any dialogues, hope you would find it interesting.
Same day evening.
Harry was hiding behind some random bookshelf in the Library to observe her target, who was sitting in his usual table near restricted section.
She had cast notice-me-not and disillusionment charm on herself, as precaution.
Her eyes moved towards Tom's bag lying on the chair next to the one he was sitting on, then back to Tom, who was writing something.
She realised that he was not going to leave his bag anytime soon, as he was still too engrossed with the same book that he borrowed earlier from the astronomy section. She thought that she might need to take some chance, as it was already getting too late.
After taking a deep breath, she went down on her knees, then slowly crawled under his table. The spells she had put on herself earlier, prevented her from his detection.
Now, the tough part, of getting her book out of his bag. Praying that her notice-me-charm would work, she slowly opened his bag while making sure not to cause that much of a movement. She looked inside and found that her potions book was not there.
Scowling towards the place where Tom was sitting, she made a decision of taking something else from his bag. Looking back she slowly pulled out his homework, then noticed something familiar in his bag. It was a black diary. Pulling it out, she realised that it was the same diary which opened Chamber of Secrets. It looked pretty new, but she knew it was the same diary which she stabbed with basilisk fang. She pocketed both his homework and diary, then crawled back to the place where she was hiding earlier.
After removing her spell, she looked back at Riddle, who was still reading the same book. Grinning she did a small victory dance then left library before he notice his missing items.
