A legendary mountain. A secret buried in ice.

A murder that echoes across Europe.

When travel writer Grace Whitmore boards the world-famous Glacier Express to Zermatt, she expects snow capped peaks and Alpine charm-not a cryptic death beneath the shadow of the Matterhorn. But what begins as a chilling murder mystery soon unravels into something far deeper: a covert surveillance project hidden in the tunnels of the Swiss Alps, a bell that never rings, and a conspiracy decades in the making.

As Grace races to uncover the truth, she must navigate whispers beneath glaciers, coded messages, and a ruthless enemy who will stop at nothing to silence her. With time running out and danger closing in, the only way to expose the truth... is to descend into it.

International intrigue meets icy suspense in this page-turning installment of the Grace Whitmore Mystery series.
