The Family Man

He stalked their homes. He slaughtered their families. But he let the mothers live.
The Family Man died twenty years ago, cheating DCI John Drake of the chance to bring him to justice. But when a mother is found with her entire family brutally murdered at an isolated house in Yorkshire, the grim discovery bears all the hallmarks of the dead serial killer's work.
Haunted by what he'd witnessed during the original investigation, Drake knows his experience makes him the obvious choice to head the specialist team investigating these latest killings. But as the deaths move ever closer to home and the killer taunts him with sly reminders of the earlier murders, Drake's forced to contemplate the unthinkable:
Are these latest murders the work of a copycat? Or twenty years ago, did Drake make the biggest mistake of his career?
