Phryne plays host to ghostly soldiers and exotic spiritualists. Aunt Prudence is swept up in the new spiritualist fad and enlists the famed Mrs. Bolkonsky to contact her dead godson, Lieutenant-Colonel Roland Claremont. The seance leaves Phryne certain there is something amiss - but it has nothing to do with the psychic realm. A message from beyond the grave leads to the death of a war veteran and Phryne uncovers a past murder that lay buried in the battle field for more than ten years - before returning to haunt the perpetrators.
