Harry and I crept to the back of the dark, dusty shop and stood by some tall shelves. The shelves had various little bottles on, all of which had different coloured liquids in. Many of the bottles had labels on them with words written on the labels that I couldn't pronounce.

"I bet half of these potions are illegal," I whispered to Harry, trying to be as quiet as possible.

He nodded in reply. He seemed to be watching my Aunt intently as she stood at the counter, seemingly unsure about what to do.

"Tulia?" my Aunt called out, in a shaky, nervous voice. "Tulia, are you there?"

We heard footsteps echo around the wooden room that we were in. A woman came out from a door behind the counter. She was tall and thin, and very pale. She had long black hair, grey eyes and bright red lips. She was wearing a red velvet dress, with a light cloak over the top. I had the very strong suspicion that she was a vampire.

"Ah! Narcissa!" the woman known to be Tulia cried, grabbing my Aunt's hand and shaking it vigorously.

My Aunt looked like she was trying to smile politely, but the face she was making looked more like a grimace. She quickly shook Tulia's hand and pulled her own away. I noticed that Tulia smirked slightly at how uncomfortable my Aunt seemed to be.

"So, Narcissa," Tulia began, leaning against the counter she stood behind, "What brings you here? I'm quite surprised you're out in public."

"Yes, well, they got impatient with him. He's not giving anything away," my Aunt snapped. I guess she meant Death Eaters when she said 'they'. I didn't have a clue who the other person she was talking about was though.

"You don't suppose he feels guilt, do you?" Tulia asked, frowning slightly.

"Merlin only knows," my Aunt replied, sighing and shaking her head. "Anyway, back to the reason I'm here. Seeing as our potions master is the one we're trying to get information out of, he won't exactly make Veritaserum for use against himself. Do you have any?"

Tulia nodded and lifted up a small section in the counter so she could get out. She made her over to the shelves where Harry and I were hiding and moved about a meter to the left of us. She reached up and took hold of a small, crystal vile, which contained a clear liquid. She made her way back behind the counter; put the Veritaserum in a small brown bag before handing it to my Aunt and receiving her money.

"Well, I'll be off," Aunt Narcissa said, waving half heartedly at Tulia, who nodded at my Aunt and wished her luck.

As we stepped out of the shop, we were both shocked by the sudden change in lighting. I squinted as I watched my Aunt disapparate, before turning to look at Harry.

Harry was sweating slightly. He looked half shocked, half excited, and he had a sort of manic glint in his eyes. I took the invisibility cloak off the both of us and took a better look at him.

"Harry?" I questioned, before poking him. He jumped slightly and looked down at me.

"What do they want to question Snape for?" he whispered, gazing off into space.

"Snape?" I asked, frowning. "Didn't he murder --?"

"Dumdbledore? Yeah," Harry answered, cutting me off. "I thought you would've known all about that."

"Not really. I didn't get told much and I'd left before he'd returned to headquarters," I answered.

"Oh, right," he nodded, and then said, "Look; we've got to get back to headquarters and tell Lupin what we heard."

Before I could fully comprehend everything, Harry had grabbed my hand and we were running back towards the Leaky Cauldron, back in Diagon Alley.
