The Callahan Chronicles

Grayscale is the first book in the Callahan Chronicles series by Paul Campbell. Set in the 1890s, this gripping narrative blends real historical events and classic literature characters into a thrilling tale of adventure, mystery, and fantasy.

When Nick Callahan's smuggling mission to Paris ends in a gruesome massacre, he barely escapes with his life, only to be saved by Marcia Kenway, a young woman wanted for her father's murder. Marcia's memory is blank, her past shrouded in mystery, and the police are closing in. Despite this, Nick refuses to turn in the woman who saved him, instead choosing to aid her in uncovering the truth.

As they dodge both the police and Dorian Gray, the man who orchestrated Nick's downfall, they find themselves entangled in a web of deceit and danger. With help from unexpected quarters, they must find Dorian Gray before he finds them. As the death toll rises and Marcia's past starts to unravel, they confront a chilling possibility: the killer might be closer than they think.

Grayscale is a whirlwind journey through the French countryside, filled with suspense, intrigue, and supernatural elements. It's perfect for listeners who enjoy historical thrillers, classic literary characters, and a dash of fantasy.
