The Spare Key: A Psychological Thriller

By Saurabh Singh

The Spare Key

She knew every mug in her kitchen.

She didn't know this one.

Mara Calder is a therapist who helps people trust their own minds. When an unfamiliar mug appears in her kitchen, followed by a mysterious spare key labeled with unfamiliar initials, she dismisses them as harmless mistakes.

Until the mistakes begin to multiply.

A document bearing her signature that she never signed. A husband with answers that are always reasonable-but never quite complete. Neighbors who notice more than they admit. A woman whose name keeps appearing at the edge of every unanswered question.

As Mara searches for the truth, she discovers that the most dangerous lies aren't shouted-they're carefully arranged to make you question yourself.

Someone has been rewriting her reality.

And if she's right, the next thing they steal won't be her trust.

It will be her life.

Perfect for readers of psychological thrillers filled with manipulation, secrets, gaslighting, and shocking twists, The Spare Key will keep you turning pages until the very last revelation.
