I bought this book expecting it to be full of gothic and mystery elements, having read other LeFanu.
I have read LeFanu's ghost stories, and the novels "Uncle Silas," and "Wylder's Hand." "Uncle Silas" is a suspense classic. "Wylder's Hand" is less of a page-turner, but has interesting characters in the mystery. Think of Dicken's "Mystery of Edwin Drood" with Wilkie Collins's dominant female characters.
"House by the Churchyard" starts with graves, re-opened crypts, and mystery. LeFanu promptly drops it to pile farce upon farce.
Much of the book relates how the residents of this small town wage "war" on each other, similar to "Lucia and Mapp." Set in the 1700s, in a small town near Dublin, featuring officers in the local regiment, the book brings high and low characters together.
There is a wealthy spinster whose charities are ill-considered. There is a mysterious stranger who has moved to town, who is surrounded by further shadows. Chapter 11 is frequently taken and printed as a ghost story--in the context of the book, the story is an extended example of how servants chatter.
We have lovers, competing small-town doctors, fortune-hunters, nubile and not-so-nubile heiresses, a professional blackmailer, debtors, rapscallions, timid lovers, a priest, an unworldly pastor, an amateur blackmailer, and some nice rabbitty little wives who are under the thumbs of their "lord and master" husbands. There is a hilarious duel-gone-wrong and drowning that never really happens.
The introduction suggests that LeFanu wrote "House by the Churchyard" out of nostalgia for the town he lived in as a youth. I think that this book is better characterized as English humor, a la "Three Men in a Boat," than as English horror. It is very readable.
I'm about half-way through, and I have found that the humor/horror ratio is about 80/20. I suppose there are still plenty of chapters in which to pack his murder mysteries towards the end.
"House by the Churchyard"--It's a wild read, for fans of Dickens, Collins, even "Lucia" novels.
