For decades, RTÉ journalist and author Barry Cummins has closely followed some of the most high-profile missing cases in Ireland. Where did they go? How many killers have got away with their crimes? He joins me next to discuss the new edition of his book “Missing: The Unsolved Cases of Ireland's Vanished Women and Children" is an account of 30 years of investigations into the unsolved cases of those who have been abducted, murdered or simply vanished in Ireland. 

He joins Ivan on this evenings show to discuss the new edition of his book.
