Once I get home from work I'll see if I can find a pic of some of the food- the downstairs was too dark to photograph.
When guests arrived, they were given a little goody bag with candy, glowstick, pen, notebook, and some misc stuff- playdoh, bubbles, stickers, that sort of thing. They were a big hit with our 20-30 year old group. About 16 people made it! We were amazed and happy.
The way it ended up being run is that teams of two were sent down to search for clues in the basement for a maximum of ten minutes- the creepy furnace room, and the even creepier root cellar. The lightbulbs had been replaced with blacklights, a body outline drawn on the floor, spiderwebs strung up, bloody handprint shower curtain added to the shower, vaguely ritualistic items laid out on a table with a very creepy candle, and clues strewn throughout, refreshed by Roomie between pairs. The root cellar also included an antique looking phone that rang and rang (there was a motion sensor) until you picked it up, and then said creepy things.
The clues included personal items, and then paper alerting people to things they needed to know to put the physical clues together. After everyone had gone, there was an accusation session in which theories were postulated and evidence was presented to support them.
Items like an ornament and a scrap of paper declaring "Ky loves Christmas" were strong contenders for my guilt, along with a pair of glasses and cupcake pot holder. Meanwhile, a Hoops and Yoyo mirror, engagement ring, and nail file indicated Roomie's possible role in the murder. But then, there was a My Little Pony lunchbox! Could it be the Brony (male fans of the aforementioned show) dressed as Nick Fury?
I was not involved in the mystery planning, so it was a shock to find out that...Roomie and I were *both* the murderesses! So that we could have the party, of course. (And Nick Fury was allowed to keep the lunchbox because he was just so excited over it.)
Prizes were awarded for 'Most Enthusiastic Crime Solvers', which went to Nick Fury and his also-Brony buddy, who scared themselves half to death in the basement, "Best Detective" for Alice and the Mad Hatter, as Alice pinpointed our guilt, "Best Costume" to Mikey from Recess, Second to Muriel and Courage the Cowardly Dog, and Third to Chun-Li and Guile from Street Fighter.
The food was much complimented, drinks drunk, and in general everyone had a really good time and it was awesome! And we got such a good response we're thinking of doing it again next year, because for a lot of our guests, this was their sole chance at Halloween celebration.
