“As a longtime TV crime reporter, I found unsolved missing children cases to be exceptionally heartbreaking and impossible to forget. To this day, one of the most haunting of those stories is the mysterious disappearance of the Klein brothers. How could three young boys just vanish after walking to a nearby park and remain missing so many years later? Jack El-Hai offers a gripping, intimate look at this nearly seventy-year-old case. Superbly written and researched, the book evinces the agony of the boys’ parents, who steadfastly refused to believe the police conclusion of drowning. El-Hai also conveys the passionate determination of more recent investigators to solve the case. This enthralling book is sure to captivate readers and, I hope, keep investigative interest alive.”
