As Harry opened the door, something brushed against his leg. He bent down just in time to grab Crookshanks by the end of his bushy tail and drag him outside.
¡°Well?¡± said Snape.
¡°I know that,¡± said Harry quickly.
Getting back into the tunnel was difficult. Lupin, Pettigrew, and Ron had to turn sideways to manage it; Lupin still had Pettigrew covered with his wand. Harry could see them edging awkwardly along the tunnel in single file. Crookshanks was still in the lead. Harry went right after Black, who was still making Snape drift along ahead of them; he kept bumping his lolling head on the low ceiling. Harry had the impression Black was making no effort to prevent this.
