On The Right Track is the eighth book in the Mysteries of Cobble Hill Farm Series.

Harriet Bailey gets a wonderful surprise when Ashley Fiske, her friend from the States, brings her young son, Trevor, to White Church Bay for a visit. Harriet cannot wait to share the village's charms with her friend, but she never predicted they would end up solving a mystery together! An unpublished manuscript by a famous British children's author named Adelaide Evergreen has turned up in Harriet's aunt Jinny's cottage. The book claims to tell the truth behind an infamous and mysterious railway crash that happened in White Church Bay in 1917, on the fringes of the Great War.

As Harriet delves deeper into the mystery, it's difficult to tell where literary license ends, and reality begins. And when it is revealed that Harriet's relative may have had a hand in causing the train tragedy, the stakes become personal. Will she find the truth at the end of the line?
