Reggie visits the archives of the Society for Psychical Research in Cambridge to see photographs taken by Crawford during his experiments, along with dozens of handwritten letters and notes. Reggie also gets a chance to see and hold a sample of historical ectoplasm, though it isn’t quite what he is expecting.
