Great characters. Good story. I missed the telling clue and was surprised when the murderer was revealed.

John Putnam Thatcher of the Sloan finds himself a bemused observer of the conflict between an established brewery making a non-alcoholic beer and selling it as a soft drink and a protest organization led by a woman who believes that this soft drink is a way to get young people to drink.
However, when the head of the protest group is murdered, Thatcher must take a more active role to identify the killer before he does more damage.
