Originally published as Some Must Watch in 1933, this is a reissue by Pushkin Vertigo under the title The Spiral Staircase – the name of the 1946 film adaptation. I’ve previously read two other novels by Ethel Lina White – The Wheel Spins and Fear Stalks the Village – and enjoyed both, although I found the former slightly disappointing in comparison with Alfred Hitchock’s wonderful The Lady Vanishes, which is based on it. This book has turned out to be my favourite of the three!
Almost the entire novel is set within the walls of the Summit, a lonely country house near the Welsh/English border. Adding to the sense of tension and claustrophobia, the main events of the story also take place over the course of a single evening. As the novel opens, we learn that four murders have recently been committed – the first two in the nearest town, which is over twenty miles away, the next slightly closer, and the fourth in another country house just five miles from the Summit. All four victims were young women and their deaths are on Helen Capel’s mind as she returns to the Summit after her afternoon off and is convinced that she sees a man hiding behind a tree in the dark.
Helen has just started a new job as ‘help’ to the Warren family – Miss Warren and her brother, known as the Professor, and their elderly, bedridden stepmother, Lady Warren. At the start of the novel, the Professor’s son and his wife are staying at the house, as is a student of the Professor’s, Stephen Rice. The rest of the household is made up of two more domestic servants, Mr and Mrs Oates, and the newly arrived Nurse Barker, who has been employed to look after Lady Warren.
When news of another murder, closer than ever this time, reaches the family, the Professor orders that all the doors are locked and everyone stays inside until morning. These should be easy enough instructions to follow, yet for a variety of reasons, one person after another leaves the house or becomes otherwise incapacitated. As a storm rages outside and the tension builds inside, Helen is forced to confront the idea that one of the remaining people in the house could be the murderer.
This book is good fun, but you do need to be able to suspend disbelief now and then (Helen is one of those heroines typical of this genre of book, who, despite knowing there’s a murderer on the loose, tries to open the front door every time someone knocks and spends most of the night wandering around the house on her own, along dark passageways and up and down dimly-lit staircases). Still, Ethel Lina White does a great job of creating an atmosphere of foreboding and fear, not just through stormy weather and shadows, but also through hints that various characters may not be as they seem. Is Lady Warren really unable to walk – and why does she have a gun in her room? And what if Nurse Barker isn’t really a nurse?
I found this a quick, entertaining read, let down slightly by the ending because the killer’s identity wasn’t particularly surprising and their motive was unconvincing. If you’re looking for a cleverly plotted mystery, I think you’ll be disappointed as I would describe this as much more of a psychological horror/suspense novel than a crime novel. It reminded me a lot of Benighted by J.B. Priestley and I think if you enjoyed one there’s a good chance you would enjoy the other. After finishing this book, I watched the film for the first time (it’s currently available on YouTube) and while it’s worth watching in its own right, I didn’t feel that it had much in common with the book!
