Glamis Castle, Angus, Scotland

[The Minister for Discord]

Nothing, it seems, guarantees centuries of angry haunting like a lifetime of secret incarceration. The imposing home of the current Earl and Countess of Strathmore is supposedly riddled with secret rooms. Residents include the so-called Monster of Glamis Castle (an unkind moniker for a deformed child held here in the 19th century), a tongueless woman running around the garden, and a wicked aristocrat who loudly bemoans a lost card game. There's also the mysterious Grey Lady. This isn't the late Queen Mother, born at Glamis in 1900, but rather Janet Douglas, executed on a trumped-up charge of witchcraft in 1537.
