Old Broadbrim's Crimson Knot

A city swallowed by shadow. A detective who has seen everything—until now.

Old Broadbrim has worked the darkest corners of Baltimore before, and he knows how to follow a trail no other man can find. When wealthy Lyman Tooker vanishes without a trace, the Quaker detective arrives confident the mystery will yield to his methods. He has never been wrong.

He is wrong now.

Every clue dissolves before he can close his hand around it. Every witness breaks before they can speak. And when a screaming man falls at his feet with claw marks raking his throat—raving about a hideous, winged creature with burning eyes—Old Broadbrim feels something he rarely permits himself: doubt.

The Bats of Baltimore are not rumor. They are real. They operate in the alleys and wharves of the Monumental City with terrifying precision, and they are watching him as closely as he is watching them.

As Old Broadbrim presses deeper, he finds a conspiracy that stretches beyond one missing man—a ruthless nephew leveraging dark secrets, a desperate young woman driven to the edge of death, and a society of monsters that wears human skin by day and something else entirely by night.

The trail grows bloodier with every step.

Can Old Broadbrim unravel the Crimson Knot before Baltimore claims him as its next vanished soul?
