Two seven-year-old boys have been abducted from the streets of Glasgow.
Both had already endured years of neglect and betrayal. But for
Detective Inspector Colin Anderson the case is especially disturbing,
because the boys look so much like his own son Peter . . .
With police resources stretched to breaking point, a simple house fire
turns into a full-scale investigation. An invisible killer is picking
off victims at random and, if Detective Sergeant Costello's hunch is
correct, committing an ingenious deception. As his squad struggles to
work both cases, DI Anderson learns that duplicity and betrayal come in
many guises. While the boys' abductor is still out there no child is
safe, as young Peter Anderson is about to find out.
