Announcing the newest walking tour from Urban Trails: The Cold Case of Ewan Mackenzie.

A cold case long buried, a granddaughter who can’t let go, a puzzle box of secrets… Can you solve the mystery that has stumped others for a century?

Today, we are officially launching our latest self-guided walking tour in the heart of Edinburgh. Our newest trail takes you through a winding ‘Celtic Noir’ narrative, blending gritty investigation with the atmospheric folklore that defines the Scottish capital. You’ll navigate through Edinburgh city, exploring the thin divide between our modern world and that which we can’t quite grasp.

The trail follows Isla, an investigator looking into a century-old mystery: the disappearance of her grandfather, Ewan.

In 1926, Ewan Mackenzie vanished without a trace, but he wasn’t the only one. Yet, the police files went cold, the families tried to move on, and the story became a footnote. But Isla has uncovered something, and she needs your help to piece together the truth.

As you move through the city, you’ll be helping Isla follow a trail that winds between historical fact and local myth. In trademark Urban Trails’ style, you won’t be alone on your journey; rich media and immersive storytelling will follow you as you self-guide your walking tour through Edinburgh’s old town and new, solving riddles along the way as you start to peel back the layers of this case, before you decide how it ultimately ends.
