Alfred Hitchcock enjoyed Chess

Shots of chess boards are quite common in movies where leisurely pursuits or an intellectual backdrop is trying to be portrayed.

Nell Snyder, played by Margaret Leighton, has been taking care of her orphaned niece and is growing more concerned over her niece's behavior.Her niece blames all mischievous behavior  on an imaginary friend named Mr. Peppercorn. When the girl's grandfather Captain King Snyder gives her a Creole voodoo doll, Nell grows even more worried. Her niece says the doll came from Mr. Peppercorn. She names it Numa and treats like a real person. Eventually, Nell begins to realize that the doll is real and that it is trying to usurp her niece's soul. She follows her niece and Numa into the forest. There, Nell frightens her away, not realizing that her niece is now the doll and the black doll has been transformed into a little black girl. She sees the doll and discovers that it bears her niece's face.and then chases the black girl into the woods hoping for a switch back.

The chess connection here is a scene where the grandfather is about to relax for a drink at a table where a chess board with pieces in original positions.

The title of this suspense flick is Where the Woodbine Twineth.

What is Woodbine? I believe Woodbine is a type of honeysuckle vine and the only time the orphan was really able to to engage Numa was where the woodbine grew or twineth!
