You were in your third year at Hogwarts School of Witchcraft and Wizardry and you had been sorted into Hufflepuff.
A supposed killer, Sirius Black, had escaped azkaban which was the most secure prison in the wizarding world. Sirius Black had somehow made it into the castle and students had been sent down to the Great Hall for safety.
All the students had been given a sleeping bag and were lined up on the floor, most of them being asleep except you as you stared up at the bewitched night sky ceiling unable to fall asleep.
You had heard footsteps and then voices approaching so you turned onto your side pretending to be asleep.
"We've searched the castle and haven't found him, Albus... perhaps it would be best if we sent the students home." You heard the cold voice say recognising it to be the potions professor and head of Slytherin, Severus Snape.
"I feel that you are right... Severus but let us tell the students tomorrow, let them sleep." You heard the other voice say, recognising it as Albus Dumbledore who was the headmaster of Hogwarts.
