About this book

A puzzling murder, secret societies, and a trail into Mexico: how far must an investigator go to uncover the truth?

In The Double Dagger by Nat Ridley Jr., a death that does not make sense sets an investigator on a search far from home. The crime is the central knot. Untying it means following a trail through a mystery shaped by hidden groups and strange symbols.
