I read this as part of a double volume (ISBN 9780897333665) with the same author's The Innocent Mrs. Duff. I made notes here on the latter novel a couple of weeks ago; I've now read The Blank Wall.
As I wrote on GoodReads, I enjoyed The Innocent Mrs. Duff a lot, but had a few small reservations. No such reservations about The Blank Wall. I'd expected I might have to work a little at this novel because I've seen both of the movie adaptations -- The Reckless Moment (1949) and The Deep End (2001) -- and therefore had a notion of the plot. Not a bit of it. I was riveted from the first paragraph and had great difficulty putting the book down for such activities as working and sleeping.
I saw The Deep End (2001) far more recently than the earlier movie adaptation, which I can remember only dimly but which I know is a more faithful rendition of the book. Part of my experience of reading the novel was thus noting the differences between Holding's original and the Tilda Swinton movie. Again, while I'd expected this to be a distraction, it wasn't: if anything, it enriched my enjoyment.
And so to the plot: WWII is still raging, and Lucia Holley's husband has been stationed in the Pacific for the past couple of years, leaving her to manage the household -- her elderly father, Mr Harper, and her teenaged children David and Beatrice -- with the help of the family's long-term housekeeper and staunch friend Sybil. Beatrice -- "Bee" -- has been seeing a man far older than herself, Ted Darby, who's obviously a snake; naturally, she reacts with hostility when mom warns her to end the relationship. In a bizarre mishap, Harper accidentally kills the sleazebag without realizing he's done so. Lucia comes across the dead Darby, realizes what's happened and, to spare her father, takes the corpse by boat to dump on a deserted nearby island. Of course, that's where her troubles begin, because the next she knows a surprisingly civilized, deferential blackmailer, Martin Donnelly, is on her doorstop, demanding $5000 as the price for returning some compromising letters Bee sent Darby, $5000 which Lucia hasn't got . . .
There's more, much more, including murder, as Lucia tries to cope with the fact that Donnelly has apparently fallen in love with her even as she has to meet the expectations and demands of her family while, she hopes, staying under the radar of the astute cop who's investigating Darby's death. Worse still, Donnelly's partner-in-crime, Carlie Nagle, a truly sinister figure, recognizing Donnelly's soft spot where Lucia's concerned, moves ruthlessly in on the situation. Lucia's sole ally is Sybil, but Sybil, being black, can do only so much in the US of the 1940s.
An extra fascination -- for me at any rate -- is that all of this drama is being playing out against a backdrop of rationing and shortages, both of which Lucia and Sybil have to deal with while struggling to avert disaster. I found the curious love story at the tale's core gripping as well. By the time I finished the book I felt I'd been on a hectic rollercoaster ride.
As an aside: When we come across racism in 1940s Hollywood movies and the like, we tend to dismiss it as being just the way things were in those days -- we don't blame the participants for their complicity, but excuse them on the grounds that they were part of the society in which they lived. Reading The Blank Wall, my opinion on that changed. Holding was writing for a pulp market -- for an audience not that dissimilar from the one queuing up outside 1940s cinemas. She was as vulnerable as any pulp author to the disapproval of her audience, yet in this novel she went out of her way to make very plain her contempt for racists and their racism, and for the appalling double standard applied by the judicial system. No wonder Holding was Raymond Chandler's favorite thriller writer.
