Chase has two compelling reasons for returning to England--a group walk along the famed Coast to Coast trail in the picturesque Lake District, and a chance to further his relationship with Mike, the handsome Devonshire coroner he met on his last trip. The walkers, including Chase's dear friend and fellow Anglophile Billie Mondreau, assemble at a Cumbrian hotel and begin their adventure with the traditional "baptism of the boots" in St. Bee's Bay. But they've barely begun traveling eastward with their genial guide than the group dynamic turns unexpectedly rocky. The problem is the Uptons--a wealthy family who have arrived from Texas, and whose squabbling antics continually overshadow the bucolic surroundings. Brock Upton, tall and commanding, is traveling with his pint-sized wife and his three siblings, along with a family friend. Every member of the party cites a different reason for joining the tour, and Chase's instincts tell him they're all lying. Brock's heart condition hinders their progress through the Lake District's hills and dales. But that proves the least of their problems when one of the Uptons is fatally poisoned. Years of secrets and grudges emerge, along with a decades-old family mystery. And only Chase's investigative expertise can find the answers--and uncover a killer in their midst before tragedy befalls the tour again.
