After barely surviving their terrifying encounter with the spectre of the hooded monk during the previous autumn, Christian Maxwell and Sam Gillespie have consolidated their romantic relationship and are starting to gain a reputation for dealing with the unknown.
For this reason, they receive an invitation to Haverford House in Wiltshire during the spring of 1817. The owners of the historic haunted manor house, Mr. and Mrs. Huxley, are being afflicted by a series of inexplicable incidents.
With his sensitivity to atmosphere, Christian is immediately alerted to danger. Yet, despite their best efforts, neither he nor Sam can discern the cause, although their search brings them closer as a couple and as a team. As sinister events develop, can our devoted duo unmask the culprit without putting themselves in danger?
