THE SPARE KEY
A Hidden Doors Thriller — Book One
by Franklin O
Nina Vale can tell when a lock has been changed—and when a client is hiding something. A rainy October call brings her to a spotless house, where a woman insists she cannot get inside. The new lock tells Nina there is more to the story than she has been told.
Then Nina finds an old brass key marked with a symbol she recognises. A photograph ties the evasive woman to someone who vanished from Nina’s childhood, and to a connection Nina’s father refused to explain. He is dead, but the past he left behind may put Nina in danger—and make her question her own part in what happened.
As Nina follows the clues, every door she opens brings her closer to a truth that someone has worked hard to keep concealed. But can she trust what she remembers, or the woman standing in front of her?
THE SPARE KEY is a tense, atmospheric thriller about family secrets, a missing woman and the risks of looking too closely at the past. Nina’s sharp eye for locks may help her find a way in—but it cannot tell her what is waiting on the other side.
