October 1911, the Condit Dam was completed, and the Northwestern Lake began to fill the canyons of the White Salmon River. October 2011, the dam was breached, and as the water receded, trees, small farmhouses, and other relics were slowly revealed. Conan and Hillary Doyle purchased forty acres on the east bank of the White Salmon River when they married in 1907 and, with endless determination, created a farm that would sustain them for years to come. In the fall of 1910, they were notified the lake behind the newly built Condit Dam would flood their farm property. They ceded the farm to the State of Washington and vacated the property before Christmas 1910. In 2011, when the waters of the lake behind the breached Condit Dam receded, human remains of two people were found in the farmhouse Conan and Hillary Doyle had built. In an effort to determine who these skeletal remains were, third-generation Conan Doyle investigates, and his findings evolve into a story about his grandparents. By the end of the story, the secret the river had hidden for a hundred years is revealed.
