Scientific Sprague

A sudden disaster on the Apache Limited throws the Nevada Short Line into chaos. A mysterious wire message reports a catastrophic wreck, but when the rescue crew arrives, they find the train unharmed-and no sign of the supposed accident. As railroad officials struggle to understand the baffling hoax, a new threat emerges. Someone is tampering with the telegraph system, sending false orders that could lead to real catastrophe.

Enter Calvin Sprague, a government chemist with a sharp mind and an unexpected talent for uncovering deception. As he digs into the mystery, he finds himself facing a cunning adversary with an unknown agenda. What is the saboteurs true goal? And can Sprague stop them before disaster strikes for real?
