When six-year-old Eric Allen vanishes into thin air one rainy morning after his dad drops him off at school, Detective Dave Munoz and FBI agent Craig Walker are called in to find out what happened. But how can they even know where to begin without a single witness or a shred of evidence? As they increasingly become convinced that the bright, handsome youngster has been kidnapped, the two lawmen also come to realize that it's not only Eric's life that hangs in the balance, but also that of the boy's distraught father. Jonathan Allen is still grieving the mysterious death of his wife a few months earlier; now, the disappearance of his son threatens to destroy what's left of his world. Munoz and Walker grimly and painstakingly piece together a complex puzzle as their investigation draws them into a tangled web of dark secrets and sinister activity that seems to stretch from some of New England's seamiest neighborhoods to some of its most posh addresses.
