The Great Keinplatz Experiment and Other Tales of Twilight and the Unseen

A doctor's visit to a troubled relative opens this collection of short stories by Arthur Conan Doyle. Sir Dominick Holden, a retired surgeon, has settled in a manor house near Salisbury Plain after returning from India. His nephew arrives through a landscape of ancient earthworks and finds a neglected drive, a dimly lit house and an uncle whose appearance suggests a hidden fear. The visitor's medical judgment offers one explanation, but the household's response to talk of unusual experiences suggests another.

In the middle excerpt, a group at a séance asks a voice about life beyond death. Their wish for proof gradually gives way to questions about belief, purpose and the dangers of curiosity. These scenes bring professional observation into contact with events that resist an easy explanation. Readers interested in ghost stories will find suspense built from anxious conversations, familiar interiors and uncertainty about what people can safely investigate.
