Farmer, Philip Jose - The Evil In Pemberley House

What a pile of poo. At least mercifully brief at 200 pages.
American girl - distant relative of Elizabeth and Fitzwilliam D’arcy - inherits famed country manor.
The house apparently has a ghost who haunts the master/mistress three midnights every year.
Other relatives in the family tree include Lord Greystoke (AKA: the Jungle Lord), as well as the Duke of Holdernesse, so Holmes is involved - or at least his notes are consulted. Oh, and the family doctor is Dr Augustus Moran, grandson of Colonel Sebastian Moran.
Far be it from me to omit, this is also a bodice ripper, and there are several passages of stripping, whipping and squeezing.
This read like very bad fan fiction to me, yet I must confess, other readers adored it.
The mystery aspect was poorly developed.
