A new cozy mystery series

The Ellen Douglas Mystery Series

A retired federal investigator. A quiet Indiana town. A small lie that refuses to stay small. The kind of mystery you start at the kitchen table and finish under the lamp.

What you can expect

Cozy, but never sleepy.

A heroine you trust

Ellen Douglas listened to her instincts for thirty-seven years on the job. Retirement did not turn them off.

A town you want to visit

Cascade has a trail, a diner, a librarian who knows your name, and a few neighbors who would prefer you stop asking.

A mystery that holds together

Clues that pay off. Suspects who feel like people. An ending that lands without cheating.

Murder in Cascade

An Ellen Douglas Mystery

All Ellen Douglas wanted was a quiet autumn walk through Cascade Park with her dog Louisa. What she found there is something she never wanted to see.

Recently retired from a long career as a federal investigator, Ellen thought small-town Indiana would be the gentle next chapter she’d been hoping for. Long mornings on the trail. Coffee at the corner diner. Quiet afternoons in the home she shares with the memory of her late husband. Then she walked into the park, and the quiet ended.
