S4·E32 Second-Hand Sofa

After recovering from a nervous breakdown, Lacey Holden and her husband, Gates, move into an apartment in the city. The previous tenant is in a hurry to catch a boat out of the country and sells her old sofa to the couple. Lacey seems happy and healthy until she fines a note stashed in the sofa that reads, "If I am missing, I have been killed on this sofa."
