"Get me a business plan." Rich spoke quietly but firmly. "If you don't know how to write one up, come by some night with some ideas and figures and I'll show you how. If there are galleons to be made at it, I can find the funds. Probably cost you..." he considered her for a moment, "twenty per cent to take on a partner with startup money. That sort of thing is more or less what I do."
"And if you want to learn your way around the muggle world, I give guided tours. The family has been making money doing business with muggles for a couple of centuries."
He shrugged. "I actually studied martial arts and the wizarding fencing from when I was a youngster. Went with the dance and riding lessons and such my mother insisted I had to learn. Grandfather set me straight on the fact that most of it would actually be useful when I got older so I paid attention. When I said back alley, I meant no rules, no bowing, fight 'til the other bloke is on the dirt or under it." He glanced around to make sure nobody was really watching and took Dora's blade. It was a solid, useful weapon. He spun it lightly in a complicated flourish before offering it back to her hilt first, blade hidden under his arm as he reached up under the back of his jacket with his other hand.
"You've shown me yours, I'll show you mine," he said with a quick smile as he brought his short blade out from where it hung between his shoulder blades. It was almost 16" long, razor-sharp and double-edged with silver runes set the length of the blade. More than one Snatcher and Death Eater had been briefly surprised that he could use and throw it with either hand. "But I start waving this big sticker around in here and somebody will call the law." He held it out to her under the side of the table away from the room.
Rich nodded. "I've mucked about with most of the usual weapons at one time or another just to learn them, but I keep coming back to the sword. Probably born eight or ten centuries too late."
