"The Mystery of Cloomber" is an early novel by Sir Arthur Conan Doyle, published in 1889. When John Fothergill West and his family move into Cloomber Hall, a secluded mansion on the Scottish coast, they discover that its former occupant, General Heatherstone, is a reclusive man tormented by inexplicable terrors. As eerie events unfold—including the appearance of mysterious Eastern strangers and a strange glow over the moor—the General's dread of impending doom becomes palpable. The story gradually reveals a dark secret from his military past in India, where his crimes during the Mutiny brought a solemn curse upon him, pursued by relentless avengers seeking justice.
