Quirrel is defence against he dark arts teacher in Harry Potter and the Philosopher's Stone Professor Snape apeaers to be trying to force an answer out of Quirrel about how to get through his Protection of the philosopher's stone(which is a producer of the elixer of life) Hary finds out he is bad. Quirrell dies as soon as Harry touches him.
I never suspected Quirrel so it was a suprise when I found that Quirrel was looking for the philosophers stone. I also liked the discription in the book.
