Every two minutes someone is reported missing in the UK. Most return, but some do not. The police are unable to investigate every case fully, and so too often these people disappear from memory. But the missing always leave behind traces – clues to who they might have been and where they might have gone.

Dave Grimstead, a retired Detective Inspector, has built an eclectic team of passionate volunteers who follow these clues wherever they lead in the hunt for answers, closure and the truth. Someone Must Know is their extraordinary story. Through ten fascinating cold cases, ranging from bodies discovered at sea to individuals who slipped through the cracks of everyday life, Someone Must Know explores the reality of what it means to search for those who are lost, to reconstruct whole lives from fragments of evidence, and to follow the stories of people who are gone but do not deserve to be forgotten.

Critic reviews

Reads to the heart and soul of what it means to be human - caring for people who are missing or unidentified and bringing them home. Heart-rending in places but utterly uplifting throughout (PROFESSOR LADY SUE BLACK, author of All That Remains)
Gripping and compassionate, it digs beneath the surface to expose the agony of those lost and those left behind (VAL MCDERMID)
Captivating and enthralling, this book carried me along in a tidal wave of page-turning intrigue. An absolutely fascinating read that I was lost in from start to finish. A brilliant book and a new voice to watch (DR DUNCAN HARDING, author of The Criminal Mind)
‘The investigative work Dave Grimstead, his colleagues and the volunteers carry out is quite remarkable. This book is a thoroughly fascinating and informative read’ (LYNDA LA PLANTE CBE)
A unique and important book of stories told with the pace of a detective novel, brimming with the mystery and intrigue of a true crime series, and shot through with real heart and hope. Dave Grimstead's vision that no missing or unidentified person should be forgotten or lose their identity, and the story of the organisation he built to ensure this, will restore your faith in people and heartily entertain you into the bargain (EVIE KING, author of Ashes to Admin)
A fascinating glimpse into a mysterious world. Thanks to Dave's dynamic storytelling the reader is constantly kept on their toes . . . I was struck by the eloquence of his insight. This passion is infectious and by the end of the book you'll want to join the team yourself (Dr Angela Gallop, author of When the Dogs Don't Bark)
