Daniel Moore is an ordinary bank employee with an extraordinary secret: he can see and speak with the recently deceased. When a young investigative journalist, Rachel Simmons, is found dead under suspicious circumstances, Daniel's ability draws him into the shadows of the city's criminal underworld. Communicating anonymously with Detective Sarah Blake via cryptic, one-use emails, he guides her through clues she could never uncover alone.

But as Sarah edges closer to the truth, the stakes rise. The killer becomes aware of their investigation, forcing Daniel to navigate a dangerous dance of foresight and invisibility. Meanwhile, the spirits reaching out to him warn of consequences, revealing that unseen forces are watching his every move.

Shadow of Truth is the fourth installment in the Behind the Rainbow series-a tense paranormal crime thriller blending mystery, psychological suspense, and the supernatural. It explores trust, morality, and the cost of walking between life and death, as Daniel and Sarah confront not only a cunning murderer but the limits of human courage and hidden truths.
