There was a long wait. Time enough for false hope to rise, and be squashed down by the memory of previous disappointments. And then, as the interval lengthened, and lengthened, that hope rose again unstoppably -
The humming began once more.
The Auror cracked.
From his belt, the Auror took a mirror, tapped it once, and then said, "This is Junior Auror Arjun Altunay, I'm calling in code RJ-L20 on cell three."
"Code RJ-L20?" the mirror said in surprised tones. There was a sound of pages being flipped, then, "You want to be relieved because a prisoner is attempting psychological warfare and succeeding?"
(Amelia Bones really is quite intelligent.)
"What'd the prisoner say to you?" said the mirror.
(This question is not part of procedure RJ-L20, but unfortunately Amelia Bones has failed to include an explicit instruction that the commanding officer should not ask.)
"He's -" said the Auror, and glanced back at the cell. The Defense Professor was now leaning in back in his chair, looking quite relaxed. "He was staring at me! And humming!"
There was a pause.
The mirror spoke again. "And you're calling in an RJ-L20 over that? You're sure you're not just trying to get out of watching him?"
(Amelia Bones is surrounded by idiots.)
"You don't understand!" yelled Auror Altunay. "It's really awful humming!"
The mirror transmitted a sound of muffled laughter in the background, sounding like it was coming from more than one person. Then speech again. "Mr. Altunay, if you don't want to be busted to Junior Auror Second Class, I suggest you buckle down and get back to work -"
"Strike that," a crisp voice said, sounding slightly remote due to its distance from the mirror.
(Which is why Amelia Bones often sits in on a coordination center of the D.M.L.E. while doing her Ministry-required paperwork.)
"Auror Altunay," said the crisp voice, seeming to approach closer to the mirror, "you will be relieved shortly. Auror Ben Gutierrez, the procedure for RJ-L20 does not say that you ask why. It says that you relieve the Auror who calls it in. If I find that Aurors seem to be abusing it, I will modify the procedure to prevent its abuse -" The mirror cut off abruptly.
The Auror turned back to look triumphantly at where the current Defense Professor of Hogwarts was leaning back in his cushioned chair.
That man then spoke the first words that had left his lips since he entered the cell.
"Goodbye, Mr. Altunay," said the Defense Professor.
A few minutes later, the door to the detention cell opened, and in walked a grey-haired woman, dressed in the crimson-tinged robes of an Auror without any sign of rank or other ornamentation, carrying a black leather folder under her left arm. "You're relieved," the old woman said abruptly.
There was a brief delay while Auror Altunay tried to explain what had been happening. This was cut short by a nod and a stark, simple finger pointing out the door.
"Good evening, Madam Director," said the Defense Professor.
Amelia Bones did not acknowledge this statement, but sat down abruptly in the vacated chair. The old witch opened the black folder and her gaze moved down to the parchments therein. "Possible hints to the identity of the current Hogwarts Defense Professor, as compiled by Auror Robards." The title parchment was turned, flipped aside. "The Defense Professor said that he was Sorted into Slytherin. Claimed that his family was killed by Voldemort. Said he had studied at a martial arts center in Muggle Asia which was destroyed by Voldemort. A request filed with the Department of International Magical Cooperation identifies this incident as the Oni Affair of 1969." Another parchment was flipped aside. "It also seems this Defense Professor gave a most stirring speech to his students, just before last Yule, castigating the previous generation for their disunity against the Death Eaters." The old witch looked up from the leather folder. "Madam Longbottom was rather taken with it, and insisted that I read the entire thing. The argument struck me as familiar, though I could not place it at the time. But then, of course, I had thought you dead."
The chief law enforcement officer of Magical Britain was now gazing sharply at the current Defense Professor of Hogwarts, across the pane of spell-reinforced glass separating them. The man in the cell returned the gaze equably, without apparent alarm.
"I shall not name any names," said the old witch. "But I shall tell a story, and see if it sounds familiar." Amelia Bones looked back down, turning to the next parchment. "Born 1927, entered Hogwarts in 1938, sorted into Slytherin, graduated 1945. Went on a graduation tour abroad and disappeared while visiting Albania. Presumed dead until 1970, when he returned to magical Britain just as suddenly, without any explanation for the missing twenty-five years. He remained estranged from his family and friends, living in isolation. In 1971, while visiting Diagon Alley, he fended off an attempt by Bellatrix Black to kidnap the daughter of the Minister of Magic, and used the Killing Curse to slay two of the three Death Eaters accompanying her. Beyond this all Britain knows the story; need I continue it?" The old witch looked up from her folder again. "Very well. There was a trial in the Wizengamot, during which this young man was exonerated for his use of the Killing Curse, not least due to the efforts of his grandmother, the Lady of his House. He was reconciled with his family, and they held a House gathering to welcome his return. The guest of honor arrived at that gathering to find his entire family slain by Death Eaters, even to the house elves; and that he himself, of cadet line, was now the last remaining scion of a Most Ancient House."
The Defense Professor had not reacted at all to any of this, except that his eyes had half-closed, as though in weariness.
"The young man took up his family's seat in the Wizengamot, becoming among the most steadfast voices against You-Know-Who. Several times he led forces against the Death Eaters, fighting with skillful tactics and extraordinary power. People began to speak of him as the next Dumbledore, it was thought that he might become Minister of Magic after the Dark Lord fell. On the third of July, 1973, he failed to appear at a key Wizengamot vote, and was never heard from again. We assumed You-Know-Who had killed him. It was a grave blow to all of us, and matters went much the worse from that day on." The old witch's gaze was questioning. "I mourned you myself. What happened?"
The Defense Professor's shoulders moved lightly, a small shrug. "You make many assumptions," the Defense Professor said softly. "For myself, I would believe that man died years ago. But if that man is nonetheless alive - then it is clear he does not wish the fact announced, and has reasons enough for silence. That man was once of some help to you, it seems." The Defense Professor's lips curved in a cynical smile. "But I am no longer surprised when gratitude is fleeting. Is there yet more that you would demand from him?"
The old witch leaned back in her Auror's monitoring-chair, looking rather startled, maybe even hurt. "No -" she said after a moment. Her fingers tapped the leather folder; nervously, you might have thought, if you had believed that Amelia Bones could ever be nervous. "But your House - there are not many Ancient Houses remaining -"
"It shall matter little to this country whether eight Ancient Houses remain, or seven."
The old witch sighed. "What does Dumbledore think of this?"
The man in the detention cell shook his head. "He does not know who I am, and promised not to inquire."
The old witch's eyebrows rose. "How did he identify you to the Hogwarts wards, then?"
A slight smile. "The Headmaster drew a circle, and told Hogwarts that he who stood within was the Defense Professor. Speaking of which -" The tone went lower, flatter. "I am missing my classes, Director Bones."
