Don't try the punch - it's very alcoholic.
All the maids, waiters, waitresses and butlers bowed, making sure they knew to follow the mansion owner's opinion to a T. If they didn't, it was sure they'd be fired, and it would probably be made sure they'd never get another job again for the rest of their lives. Letters were handed out, except to one waiter. He kept his head bowed, and looked only slightly shocked when the letter in his hand turned out to be fiery red. The other people there gave him awkward looks, pitying the young boy who'd only joined a week or so ago.
The doorbell rang as the hired actors stood at the door. Some were to arrive later, and they all had separate jobs. The ones arriving later were supposed to look shocked, as the 'contestants' or rather, 'guests' were probably going to look. All of them were hired to confuse the actual guests there, and every single food item had been contaminated with some sort of delayed sleeping drug, a really strong one. The actors were all given the antidote, so only the people who had to would fall to the ground at the right time.
It was cleaned spotless, as it should be. Only a grand piano sat in the centre of the ballroom, prepared for one of the actors to play it. As the people flooded into the room, the waiters and waitresses offered 'nibbles' to all those attending, a smile on each of their faces. The actors were incredible, some looking incredibly drunk, some looking incredibly bored, and some looking like they're having the most incredible night in their life. The carriages would be arriving with the special guests soon, and they all had to prepare for the worst.
