Dave Porter has just left the halls of Oak Hall and traded his schoolbag for a civil‑engineer’s hard hat. Assigned to a bustling Texas construction site, the bright‑eyed youth is eager to put his training to work, but a simple slip of paper soon pulls him off the blueprint. A puzzling letter from a cobbler in a nearby town mentions two pairs of shoes he never bought, hinting that someone else is using his name.
Curiosity gets the better of him, and a brisk sleigh‑ride with his sister Laura turns into a trip to the mysterious shop. There, Dave discovers a stranger who looks exactly like him—a “double” whose presence threatens to upend his plans. As the pair of look‑alikes cross paths, rumors of the vanished Basswood fortune surface, and the young engineer finds himself caught in a web of mistaken identity, hidden motives, and a budding adventure that promises more twists than any classroom lesson.
