A little late - my apologies!
Neville took a deep breath to steady his nerves. HIs pulse was racing and he was certain his hands were trembling. All because he knew it. He knew the answer!
Looking up, he caught Ginny's gaze across the table. Suddenly, Neville found himself doubting his previous certainty. Was he wrong? Had he made an error in his deduction? Ginny smiled at him as her left eyelid flickered in a wink. Neville found that comforting.
Breathing in, he nerved himself to speak out. It was his turn after all.
"I accuse Auror Umber, in the Owlery, with the Bottle of Antiquity."
“I've got a lead for you Harry,” Hermione exclaimed as she bustled into his office. Harry looked at her blankly. “On the unusually high number of Roman artifacts flooding onto the antiquities market,” she prompted.
“Oh yeah. That. What's the lead?”
“I've managed to track a shipment back to a warehouse in Lancashire. I want you to come and check it out with me.”
Harry objected - after all, she was the civilian and he was the professional, but eventually they did it Hermione's way.
They were astonished to find Nevillle Longbottom crouched in a converted weaving shed, cackling maniacally as he carefully sprinkled something from a plain-looking bottle over a clunky, roughly handmade pottery cup. When the tatty slipshod pottery cup turned into a fine artifact they were almost silent.
“I don't believe it!” Hermione breathed. “He's got a bottle of antiquity!”
“This is Gran's pride,” Neville said, laying his hand on an unassuming terracotta vessel. “She calls it her bottle of antiquity.”
“But it's not a bottle,” Hermione objected. Neville shot her a long-suffering look from under his eyebrows.
“We all know that, but still, that's what she calls it.”
“So does it do anything? I've not read anything about a Bottle of Antiquity.”
“Yeah. Any water poured into it turns into wine.”
“Wow!” Ron perked up with visible interest. “Sounds like a winner Nev.”
“Not really Ron. Have you ever tasted two thousand year old wine? 'Cos I have, and I can tell you it's really an acquired taste.”
