I had initially thought I would enjoy this book which is a trilogy of shorter tales rather than a novel, although there are connecting characters and an underlying theme. The hero, only 16 at the start, is an engaging young would-be detective Xavier Kilgarvan, whose heroes include Sherlock Holmes. A horrifying case occurs at a mansion belonging to another branch of his family - where two uncles live and the three daughters of the eldest, both being brothers of his father. Xavier's father has been disinherited and ostracised by the rest of the family, and as the stories progress the general consensus is that this was unjust.
Xavier falls for his young cousin Perdita, one of the three daughters in question, and his life is governed by his unceasing passion for her despite her faithless and generally sociopathic behaviour. Meanwhile he remains oblivious to the unrequited love of her sister Therese, who is good-natured, intelligent and self-sacrificing.
The first story is a tragedy, where Xavier keeps secret the solution given the scandal it would cause the other branch of the family. Although it is effectively spooky in places, it is rather a cheat in that the detective genre which this supposedly fits into (the author's afterword makes it clear that in her five gothic novels she tackled particular genres, and the detective-mystery genre was the target here), it has a solution which would never be contemplated in any genuine story of the genre since it is entirely supernatural.
In the second story, echoes of Jack the Ripper and similar serial murders are evoked. Xavier is now twenty-eight, and lives in New York where he makes a successful living as a detective, but he returns to Winterthurn to try to track down the killer. He soon knows who it is, but his difficulty is in proving it. The reader also knows early on if they picked up on the MO used to kill a certain character's sister in the first story. The case ends ignominiously for Xavier when the killer presents a supernatural excuse for his crimes in court, and it is Xavier's own family who end up suffering, with him being cut off by his own parents as a result. He now seems permanently estranged from Perdita also, and she informs him of her decision to marry a good Christian man who will counteract her perceived inner evil.
In the final story, Xavier is having a midlife crisis as his fortieth birthday approaches. He responds to an anonymous summons back to Winterthurn and arrives shortly after a gruesome triple murder at the vicarage which, over time, leads directly to the rekindling of his relationship with the now widowed Perdita. Xavier is convinced of the killer's identity, pursues him, and eventually the community is also convinced he is right - yet he suffers an existential crisis and lives at a friend's for months, sunk in depression. There is a supposed happy ending for Perdita and he, and yet I couldn't help thinking that the real killer was much closer to home given certain clues dropped into the story. I found myself growing increasingly impatient with Xavier, especially in the final story. I also felt sorry for the ever faithful Therese, although her eventual 'settling' for a good man was probably the best thing she could have done.
The stories are held together by the interjections of an editor who in some places has omniscient insight into the thoughts of the characters - even those who die immediately afterwards without passing on those thoughts to anyone - and yet at other times is totally ignorant of what happened (a case in point being the 'quicksand' episode in the second story). The style is also a very laboured pastiche of 19th century style, not seen in actual classic novels, and in any case inappropriate - the editor makes it clear that he or she is writing some time after the last case which occurred shortly before WWI. So a more appropriate style would be something along the lines of Erskine Childers' "Riddles in the Sand" or even Agatha Christie whose first novel was published in 1920, not this laboured cod-Victoriana. All in all, I found this book rather a disappointment and am therefore rating it at an OK 2 stars.
