Morton Farrier was no longer at the top of his game. With his career in forensic genealogy faltering and no new cases to work on, Morton decides to focus on finding his own biological father. But when a mysterious woman abandoned in the midst of the Battle of Britain begs him to uncover her past, Morton can't help but accept the challenge. What Morton discovers is a secret document with links that could expose the wrongdoings of powerful people who want its contents to remain hidden forever.

This thrilling fifth book in the Forensic Genealogist series can be enjoyed as a stand-alone story, but if you enjoyed Agatha Christie's Murder on the Orient Express, you'll love uncovering the secrets in The Spyglass File. Join Morton on his quest for the truth!
