.. How can I get hints in the game?

As usual, this is a lot easier for Amateur players than for Masters. The Amateur players have a hintline on their phones, as well as a detailed task list. The Master players don't have these things, but they can call Bess, Jon, and Professor Hotchkiss; they may or may not be able to help, but the things Nancy has to say will at least give you an idea of what's on her mind.
