### Answer

Brute force will tell you that
Alice has L, Barry has H+K+N, Charlie
has I+R+Y, Dawn has Ö+P+Q+J, and Edgar
has B+E+T. V is one of the Black Vienna.
In addition, Barry must have one of G or X.
So must Charlie. So Alice must have F and O.

Edgar is the only player with C or Z.
He cannot have both. He knows that, too,
as you cannot have any not in AKMOSU. If
he had neither, he would have known the
answer, so he has exactly one. Which one?
Note his early guesses: BLM, JTY, DJZ, HUZ.
He always guessed a card of which he held
exactly one spy. That suggests he has Z.
Therefore C is in Black Vienna.

Now, Alice is the only player who can hold
D or W. She must have exactly one
of those; she's known to have L+F+O, so she cannot
have both, and if she had neither, she would have
guessed earlier. Her last question was to ask
DLS of Barry. Why? She knew she had L and she
knew you had S. No one knew Barry didn't have D
until that question, except Barry. So she needed
to know. Therefore, she doesn't have D, which
means D is in Black Vienna.

Therefore, Black Vienna is probably CDV. We also know
that Alice held FLOW, Barry HKN and G or X,
Charlie IRY and G or X, Dawn JÖPQ, and
Edgar BETZ. It is more consistent with Barry's
guessing pattern that he holds G, but it's not
clear, as he is a strong player.
