"The other's in Borgin and Burkes," said Draco, "and they make a kind of passage between them. Montague told me that when he was stuck in the Hogwarts one, he was trapped in limbo but sometimes he could hear what was going on at school, and sometimes what was going on in the shop, as if the Cabinet was travelling between them, but he couldn't make anyone hear him ... in the end he managed to Apparate out, even though he'd never passed his test. He nearly died doing it. Everyone thought it was a really good story, but I was the only one who realised what it meant-even Borgin didn't know. I was the one who realised there could be a way into Hogwarts through the Cabinets if I fixed the broken one. Hermione and Theo helped me."
