M., this exact thing just happened to us during the Christmas holiday. Imagine how horrible it was to want to smell the pine tree and all the nice smells that come with Christmas and we are having to smell a dead animal. Unfortunately it was in our dining room next to our kitchen, so that made things worst. I could not have any company over because I was to embarrassed. I did call an exterminator to see what to do and he advised that there is really nothing you can do but to wait it out. He also said that when its cold outside, then the smell will linger longer because the body fluids or whatever (yuk) dont dry up as fast as it does when its hot outside. We actually asked him if he would just come and cut a hole where we thought it was and take it out and he said that he could but he did not recommend that because they have found that you might think you know where it is, but then when they have made this huge hole in your sheetrock, it turns out that it is not there. Anyway to make a long story short, he said it would be too costly and if we could jut wait it out for about a month, then the smell will go away. I have to say that it was a little over a month and now the smell is completely gone. I feel sorry for you and I know what your going thru, but buy some candles and mask the odor the best you can. BTW dont put the glade plug in fans in the wall where you think it is because I did that and it made it worst. Good luck!!
