Blame: What happened the day Moaning Myrtle died?
The first person to discover her body was, of all people, Olive Hornby. The girl screamed when she saw the body, and her scream echoed through the empty bathroom to the corridor.
Myrtle, who was as yet just a shadow of a ghost, watched with interest the gathering crowd. It was, after all, the most attention she'd ever received in life or death.
Professor Dumbledore pushed to the front of the crowd and stood stock still at the scene before him. Myrtle could see the rest of the crows through the door of the toilets, and she felt quite impressed at the turnout. Soon, however, the proceedings grew quite a bit boring as the professors dispersed the crown. They huddled together, discussing the situation in soft voices.
Myrtle, beginning to get control over her ghostly form, swooped a little bit closer. Professor Dumbledore's eyes flicked toward her briefly. He soon had Professor Flitwick levitating Myrtle's body out of the lavatory, and the rest of the teachers followed.
Professor Dumbledore, however, stayed behind. "Hello, Myrtle," he said once the others had left.
"You can see me, Professor?" She was, needless to say, in a little bit of shock.
"Of course, dear girl. I see you feel you have some unfinished business here."
"Well, I'd like to get back at that thing that killed me!" Here she broke off into sobs. Dumbledore made some soothing noises.
"Could you tell me, perhaps, what happened when you died?" Myrtle, so freshly deceased, cried while she told him. She was still hiccupping while he stroked his beard thoughtfully. "Thank you my dear. I fear I must leave you now. Happy haunting." As he left, Myrtle settled disconsolately onto the toilet in the stall in which she'd died and decided to see what would happen.
