But as it turned out, Quirrell's lessons were a bit of a joke. His classroom smelled strongly of garlic, which was for protection from vampires if the rumours were believed. He stuttered so badly it was almost impossible to understand what was being said, and the stench of garlic tended to make their eyes water. But despite the difficulties Harry was enjoying what he learnt from the books and what Marcus Flint taught him at night in their tutoring lessons, Marcus didn't have a problem with helping and was quite happy to pass off all his old notes and books from his previous years. Dumbledore was pleased with the revelation that the Riddle heir was doing so well in a defence class and mastering the theory behind light spells so easily.
