I'm attending a murder mystery party Thursday night, and aside from one or two acquaintances, I won't know anyone there (it's a networking thing). I have my invitation with my character description and a few instructions, like find Jane Doe and reveal xyz, but aside from that, I don't know what to expect. I'd prefer not to make an ass of myself. :-)
Any tips? Also, any suggestions on a gift for the hostess? Bottle of wine, maybe?
