Review of L. T. Meade and Robert Eustace, “The Luck of Pitsey Hall” in A Brilliant Void: A Selection of Classic Irish Science Fiction, edited by Jack Fennell (Tramp Press, 2018): 151-176 — Purchase here. Reviewed by Sara L. Uckelman. (Read the review of the anthology).
This is a pretty classic Gothic story, leaning more towards psychological horror than to science fiction, though there are elements of the uncertain and unknown that stem from a possibly scientific origin. The key figure in the story is the mysterious Madame Koluchy, renowed physician and healer who is able to effect miraculous cures, though scientific tests performed upon her drugs and medicines show them to be no different than those used by other doctors.
Mysterious Madame Koluchy may be, but she is also rather nefarious. Shortly into the story she is implicated in a murder, and other secrets and possible crimes come to light. By the end, we are still left with a veil of uncertainty; who killed Delacour, and why?
