The Head of Slytherin House felt like he had been through the wringer. Dumbledore had interrogated him for close half the night and nearly all of the next day, with but a one-hour break after lunch. Again, and again he had Snape tell him about all the places he had looked for Potter and where he had finally found him. How he had discovered Voldemort's return and why he had not sent word to the Order. Of course, the headmaster had agreed that rescuing Harry had been the priority. But if he had known about the Dark Lord's return, he could have initiated steps to protect the wizarding world from this madman.
