If he had wanted to be some sort of detective, like the protagonists of Michael's childhood books, Anthony would have become a G-d damned Auror.
He had been briefly tempted by the offer after the war, some delusion of becoming a Nazi hunter drifting back and forth in his mind. But when Longbottom and Weasley and Potter and the lot of Gryffindors went off to the rebuilding Ministry, Anthony repeated his seventh year instead. Some residual cowardice, he supposed. Anthony Goldstein had simply survived the second of May, 1998. He was neither a war hero nor a wizarding Simon Wiesenthal.
So Anthony Goldstein went to law school (accepting that ill-mannered jokes about Jews and lawyers would be inherent to the whole business) and took satisfaction in defeating Death Eaters with words and arguments instead of hexes and raids.
Occasionally, though, the business of constructing those arguments felt suspiciously like Auror work.
Take this case, for example. It was an ugly attempted murder case, with hints of necromancy and human sacrifice within the submitted statements so far. There was a link missing, though, one that would prove beyond a shadow of a doubt the link to dark magics. Technically, the paperwork and analysis of all of this was solicitor, not barrister work, but there were never enough hands in Prosecution Services for both on each case. Tony didn't mind, usually. Piecing together a narrative from the evidence was just a puzzle. Like most Ravenclaws, Anthony enjoyed a puzzle.
But his O on his NEWT in Ancient Runes was not enough to decipher these runes. His rustier understanding of Ancient Aramaic wasn't helping, either. Tony found himself hitting his head against a wall in both the metaphorical sense and the literal. His deskmate, concerned, suggested that Goldstein perhaps eat something. At least a single calorie, if not more.
Tony brought the file of evidence with him to the canteen, of course, along with a book of Mesopotamian runes and a legal pad. Stared at the photographs again as he waited in line, absentmindedly filling his tray with a bowl of paneer butter masala and a butterbeer. Stared at it more as he walked to the nearest empty table, spreading it out in front of him to gaze at as he blankly consumed spoon after spoon of mild curry.
He was dimly aware, with the refined paranoia of both a descendant of a Holocaust survivor and a member of the resistance at Hogwarts in 1997, that someone was watching him. Following him, even. Tony let it go on a few minutes, in the line and as he settled into a table.
SCRK.
The sound of a metal chair scraping against the tile was loud and distinctive in the mostly empty canteen. Tony sighed, dropping his spoon into the bowl and flipping the photograph over. "If you want to look, you could ask," Tony announced, only slightly exasperated. He twisted around to look at his tail, blinking as he tried to place her. Ravenclaw, certainly. Started with a P? Not a relation of Padma's, he vaguely remembered asking Padma that once.
Instead of admitting he couldn't remember her, Tony just shook his head. "Course, I'd have to tell you to sod off, probably. But asking is generally the polite thing to do." There was empty seats all around Tony's table -- he nodded his head towards one of them, then to her, before turning back around to his lunch.
