"Bony stood up and walked slowly across the room towards me. His eyes were rimmed with red as he reached out and took my hand. He gave it a flaccid shake, but it was a gesture I found myself unable to return.
"'I'm sorry, Jacko,' he said, as if I, and not Bob Stanley, were his confederate.
"I could not look him in the eye. I turned my head away until I knew that he was no longer near me.
"When Bony had slunk from the room, looking back over his shoulder, his face bloodless, Mr. Twining tried to apologize to the headmaster, but that seemed only to make matters worse.
"'Perhaps I should ring up his parents, sir,' he said.
"'Parents? No, Mr. Twining. I think it is not the parents who should be brought in.'
"Mr. Twining stood in the middle of the room wringing his hands. God knows what thoughts were racing through the poor man's mind. I can't even remember my own.
"The next morning was Monday. I was crossing the quad, tacking into the stiff breeze with Simpkins, who was prattling on about the Ulster Avenger. The word had spread like wildfire and everywhere one looked knots of boys stood with their heads together, hands waving excitedly as they swapped the latest—and almost entirely false—rumors.
"When we were about fifty yards from Anson House, someone shouted, 'Look! Up there! On the tower! It's Mr. Twining!'
"I looked up to see the poor soul on the roof of the bell tower. He was clinging to the parapet like a tattered bat, his gown snapping in the wind. A beam of sunlight broke through between the flying clouds like a theatrical spotlight, illuminating him from behind. His whole body seemed to be aglow, and the hair sticking out from beneath his cap resembled a disk of beaten copper in the rising sun like the halo of a saint in an illuminated manuscript.
"'Careful, sir,' Simpkins shouted. 'The tiles are in shocking shape!'
"Mr. Twining looked down at his feet, as if awakening from a dream, as if bemused to find himself suddenly transported eighty feet into the air. He glanced down at the tiles and for a moment was perfectly still.
"And then he drew himself up to his full stature, holding on only with his fingertips. He raised his right arm in the Roman salute, his gown fluttering about him like the toga of some ancient Caesar on the ramparts.
"'
"For a moment, I thought he had stepped back from the parapet. Perhaps he had changed his mind; perhaps the sun behind him dazzled my eyes. But then he was in the air, tumbling. One of the boys later told a newspaper reporter that he looked like an angel falling from Heaven, but he did not. He plummeted straight down to the ground like a stone in a sock. There is no more pleasant way of describing it.”
Father paused for a long while, as if words failed him. I held my breath.
"The sound his body made when it hit the cobbles," he said at last, "has haunted my dreams from that day to this. I've seen and heard things in the war, but nothing like this. Nothing like this at all.
"He was a dear man and we murdered him. Horace Bonepenny and I murdered him as surely as if we had flung him from the tower with our own hands."
"No!" I said, reaching out and touching Father's hand. "It was nothing to do with you!"
"Ah, but it was, Flavia."
"No!" I repeated, although I was a little taken aback by my own boldness. Was I actually talking to Father like this? "It was nothing to do with you. Horace Bonepenny destroyed the Ulster Avenger!"
Father smiled a sad smile. “No, he didn't, my dear. You see, when I got back to my study that Sunday night and removed my jacket, I found an oddly sticky spot on my shirt cuff. I knew instantly what it was: While joining hands to form his distracting prayer circle, Bony had pushed his forefinger inside the sleeve of my jacket and stuck the Ulster Avenger to my cuff. But why me? Why not Bob Stanley? For a very good reason: If they had searched us all, the stamp would have been found in my sleeve and Bony'd have cried innocence. No wonder they couldn't find it when they turned him inside out!
"Of course, he retrieved the stamp as he shook my hand before leaving. Bony was a master of prestidigitation, remember, and because I had once been his accomplice, it stood to reason that I should have been so again. Who would ever have believed otherwise?”
"No!" I said.
"Yes." Father smiled. "And now there's little more to tell.
"Although nothing was ever proved against him, Bony did not return to Greyminster after that term. Someone told me he had gone abroad to escape some later unpleasantness, and I can't say I was surprised. Nor was I surprised to hear, years later, that Bob Stanley, after being ejected from medical school, had ended up in America where he had set up a philatelic shop: one of those mail-order companies that place advertisements in the comic papers and sell packets of stamps on approval to adolescent boys. The whole business, though, seems to have been little more than a front for his more sinister dealings with wealthy collectors.
