The rite of the Musgrave family

A former acquaintance of Holmes from college, the aristocrat Musgrave, turns to the detective about the mysterious events taking place in his castle. The other day, the butler was seen surreptitiously looking over a family document called the Musgrave Family Rite. The owner wanted to fire the butler for such blasphemy, but he suddenly disappeared.
The maid, who had an affair with the missing man, goes crazy and suddenly disappears. Holmes believes that the document the butler was interested in is important to the case because the butler risked a good job when he went for it.
