In a war when so many dead were lost or simply dumped into shallow graves, the Trench Detectives come across a body buried with care on a battlefield where tens of thousands of soldiers died in 1915. As forensic scientists struggle to decipher the engravings on the soldier’s corroded ID tag, another team of experts tease apart a leather pouch the man was carrying. In it are three rings: A pair of matching rings each inscribed with a surname and a date and a third ring that bears the Iron Cross …..keepsakes with meaning for this fallen soldier. An intensive investigation with many twists and turns finally yields the identity of the Fallen, bringing the trench detectives face to face with his descendants.
