Haunted Honeymoon (1940)

Amateur detective Lord Peter Wimsey is to be married to crime novelist Harriet Vane, at a big Society wedding. Harriet has little charms made so that they both promise not to get involved with any more crimes as they are 'retired'. As a wedding present, Peter purchases the old Jacobean home where Harriet grew up, "Tall-boys." After the wedding, they go to their new house to get the keys from the previous owner, Noakes, who now has money but has no intention of paying wages or any debts that he owes. Upon arriving at the house, Lord and Lady Wimsey find no one at home and finally borrow a key to get in. They have supper and retire for their honeymoon. The next day, people arrive to clean the house, the chimneys, and the grounds, and they find Noakes' body in the cellar. Lord and Lady Wimsey try to stay out of this murder as they promised, but that might not be so easy.
