The Morning After, the Night Before

Mrs. Hudson has a plan:

1) Lure the boys in with rum cake and mulled wine.
2) Make sure they notice the mistletoe.
3) Shoo them upstairs.
4) Well… we don’t need to lay out all the details, do we, dear?
5) Harass them until they’ve finally talked it out like grown-ups.
6) Compare notes with Mrs. Turner
