People seem to love dressing up in costume and going to parties. If the mask is good enough, even the best of friends can’t identify the wearer. This allows freedoms to say and do things that perhaps the participant would never do.
Some masquerades are quite elaborate. They take place at huge houses or McMansions. There are spiraling staircases, gilded trimmings, caterers about and even an orchestra playing dance tunes. Decorum is maintained according to caste expectations.
During Halloween there are also parties, but they might feature salads made up to look like human insides, games designed to gross out participants, and freaky music echoing off the walls.
Your task is to write a scene in which a masquerade plays a major role. Make things interesting by having something unexpected and untoward happen. Think murder or grand theft. Perhaps an unwanted sexual encounter. Stumbling drunks and flirtatious behavior.
The setting is crucial. Readers want to be drawn in by opulence or the fright-factor. Descriptions of what participants are wearing is also important. When the story gets going, dialogue will make things come alive.
Have fun with this one.
