In 1895 a group of the Royal Parapsychological Society meets to test a medium who claims to have psychic powers.

First they tie her up.

Then they arrange the testing tools for her to see: crop, whip, ice, feather etc.

Then they blindfold her.

And then they take the tools, one by one, and ask her to tell which tool they have picked. After she answers they let her sweat a little (“A crop you say. Well…”)

If she is correct the tool is put aside. If not, they use on it on the fake psychic.
