Richard sighed as he walked to the front door. It was another example of his truism that magical people knocked, non-magical rang the doorbell. Given the occasion of Tonk's visit, any humor would probably be... graveyard humor. The older Tonks he remembered would probably have appreciated it. This girl, probably not.
He could still do a salesman's face; he put on a polite smile when he opened the door without bothering to look out through the peephole. The wards he kept on his house and property were good enough to tell him someone's shoe size. He had magically followed his visitor from the time she came through the front gate. As he opened the door, he touched a hand to the wall next to the door and quietly said the few words that re-established the Unplottable spell on his estate. No sense in risking unwanted visitors, although that seemed to be less of a problem these days.
"Hey Tonks, thanks for coming out." He kept his voice even, a slight smile on his face. After all, the girl was alive in this here and now. He held out a hand for a gentlemanly handshake. "I've got a bottle of what will be one of your favorites on the kitchen table for you. Unless you'd rather the back patio? My opinion, this is the sort of thing requires a little strong drink and some quiet words."
He waved Tonks in and led the way towards the back of the house while he waited to hear her preference.
"What do you know of Grindlewald and the whole Wizarding War? And have you ever heard of Lord Voldemort?"
