Someone Must Know: The Search for Missing People and Lost Identities

Dive into the compelling world of cold cases and unsolved mysteries with Someone Must Know. This gripping true crime account explores the enduring search for individuals who have vanished, leaving behind only fragments of evidence. Written by retired detective inspector Dave Grimstead, the book details the vital work of Locate International, a dedicated team committed to following the faintest clues across decades and borders.

Every ninety seconds someone is reported missing in the UK, and while most return, this book focuses on those who remain lost. Discover how experts reconstruct entire lives from seemingly insignificant traces—a scrap of wet paper, an old dress, or a faded photograph.

• Examines riveting cold cases, including the mystery of a tall man found at sea with weights tied to his ankles, and a mother who disappeared without a trace.
• Profiles the work of Locate International, a volunteer team comprising oceanographers, genealogists, forensic linguists, and more.
• Offers a study in reconstructing lives from fragments of evidence for those who are gone but not forgotten.
• Praised as 'Heart-rending but utterly uplifting' by PROFESSOR LADY SUE BLACK and 'Gripping and compassionate' by VAL MCDERMID.
