Singing to the dead

the long version

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 ... Then, with police resources stretched to breaking point, a simple house fire turns onto a full-scale murder hunt. An invisible killer is picking off victims at random and, if DS Costello's hunch is correct, committing an ingenious deception.
