The wife could be reading a book on how to hide a body. Could be a real book. The gardener could be planting seeds to grow a tree over the body of the man to hide him. The butler could be shining the silver, say silver of a knife that he just cleaned. Why'd he clean it? BLOOOOD. The maid was out getting the mail..... Yeah, I don't know how to spin that one But a lot of people assume it is the maid. The cook could be making breakfast. Maybe bacon. OF HUMAN MEAT! ........Disgusting person.
Maid is the KILLER but it could also be the: Wife - she is not a wide reader/she don't know how to read/she doesnt even have a book!. Lol Gardener - does he/she even have a dayoff. It's sunday. Lol Butler - they're not rich. They doesnt have a butler. Lol Cook - he/she already made the breakfast earlier (what will the ppl in the house eat before doing their job, eh?) Lol
The maid. For all my Harry Potter lovers out there "There's no post on sundays!" Post offices don't run on Sunday's. Duh??
