The Locked Letter
By Raj Kumar Gautam
When investigative journalist Ishita Roy receives a bloodstained letter linked to a decades-old disappearance, she joins reclusive forensic analyst Aarav Mehta to uncover the truth behind Amrita Kaur - a girl who may never have existed.
But the deeper they dig, the more reality fractures.
The letter isn't just evidence.
It's a weapon.
A psychological virus designed by a secret experiment called Project Lachesis, where trauma is rewritten, memory is manipulated, and guilt is engineered.
As murders begin to mirror unpublished chapters, and readers of the letter start dying in patterns, Ishita and Aarav realize they're not solving a mystery - they're living inside one.
And the final twist?
The book doesn't end when you finish reading.
It ends when you forget who you are.
