It's Christmas 1857, snowing outside, and Mrs Smith is ever so excited as her guests have joined her for a Christmas Eve dinner. The evening begins well enough. The tree is looking lovely. Gingerbread has been baked. Even the maid has agreed to sing a wee song.

Join us and enjoy your 3 course Christmas dinner but alas, during the dinner, someone altogether unexpected turns up and more than one person is not at all happy. It doesn't end well and, in fact, at the end "There's been a murder!!"
