Valley of the Shadow

While out on a walk, Eleanor Trewynn, her niece Megan, and her neighbor Nick spot a young, half-drowned Indian man floating in the water. Delirious and concussed, he utters a cryptic message about his family being trapped in a cave and his mother dying. The young man, unconscious and unable to help, is whisked away to a hospital while a desperate effort is mounted to find the missing family in time.

The local police inspector presumes that they are refugees from East Africa, abandoned by the smugglers who brought them into England. While the Cornwall countryside is being scoured for the family, Eleanor herself descends into a dangerous den of smugglers in a desperate search to find the man responsible while there is still time.
