A Mysterious House

Publisher's blurb:

Carter, felt strange vibrations as we entered the house. His little pendulum whirred.
"-Is anybody home?" No answer...
We took a few more steps into the living room, only to find that four people were sitting silently. With a nod, they invite us to do the same, join hands and close our eyes... We comply.
After all, that's what we'd come for, to "experience the energies within us" - that's what it said in the advertisement for a newspaper dedicated to the occult.
I can hardly believe what I'm writing in my notebook today, but I have the nagging impression of having traveled through space that day...
