In Sherlock Holmes’s story “The Adventure of the Musgrave Ritual,” the Musgrave family estate is called Hurlstone.
The case is presented as one of Holmes’s earliest investigations, told by Holmes to Dr Watson after the detective discovers an old memory in his files. Reginald Musgrave asks Holmes to investigate the disappearance of two servants from Hurlstone, including the butler Brunton.
The mystery centers on an ancient ritual containing questions about where a family ancestor stood, walked, and was buried. Holmes interprets the wording as a set of directions across the estate rather than as a ceremonial text.
Hurlstone is sometimes confused with Baskerville Hall, another famous country house in the Holmes canon. The Musgrave case differs because its solution depends on the physical layout of the estate and a historical secret hidden beneath it.
