About D. R. Becker

D. R. Becker writes immersive thrillers that blend mystery, history, travel, and danger.

His debut novel, Murder on the Rhine, follows four longtime friends whose river journey through Europe takes an unexpected turn when they become drawn into a mystery rooted in the past.

Inspired by a lifelong interest in travel, history, and the hidden stories behind real places, Becker creates fast-moving suspense with mature protagonists, evocative settings, and puzzles that unfold along the way.

Murder on the Rhine is the first novel in the Callahan & Harrington series.

Why These Stories

Travel has a way of making history feel immediate. A cathedral, a river, an old street, or a castle can turn something from the past into something you can suddenly see, touch, and imagine.

That intersection of place, history, and mystery is what draws Becker to these stories. Murder on the Rhine grew from the idea that an ordinary journey through extraordinary places could become something far more dangerous.

The Callahan & Harrington series is built around that same idea: compelling mysteries, real destinations, mature characters, and adventures that invite readers to follow the journey.
