From 1950 to the present day, there have been almost 900 long-term missing people in Ireland. The equivalent of a vibrant village, all gone, vanished without a trace.

Where did they go? Are they dead or still alive somewhere? How many have been murdered? How many killers have got away with their crimes?

RTÉ journalist Barry Cummins has reported on the unsolved cases of Ireland's missing for decades. In this new edition of his bestselling book, he examines the latest leads and developments of Ireland's most high-profile missing cases, including the women who disappeared under eerily similar circumstances in the 1990s and whose bodies have never been found.

Written with the assistance of the gardaí and the families concerned, Missing is a comprehensive and shocking account of the cases that have in turn fascinated, puzzled and horrified the Irish public. It also examines the possibility that there may be a serial killer out there who has gone to extraordinary lengths to evade justice, leaving open the possibility that they could strike again.
