It is 1926 in the remote camp town of Scenic, Washington, and Billy, Dannie, and Finn have more on their minds than the upcoming Fourth of July pageant. When Billy finds a mysterious burlap sack containing a threatening note, he and his best friends have brand-new case to solve. Does the note have something to do with the mysterious, unscheduled trains that are moving through Scenic? The trail leads to a planned railroad heist of a special train that carries raw silk worth millions from the Seattle shipyards to the East Coast textile mills. But time is running out as the three friends frantically search for clues to the identify of the robber before the targeted "ghost train" passes through Scenic. Anne Capeci's latest book in this fast-paced historical series offers young readers a satisfying mystery, well-drawn characters, and an authentic portrait of the rough-and-tumble life of a western camp town in the 1920s.
