While her starfaring people are being hunted by an implacable enemy, a young caver discovers a traitor in their ranks and must undertake a transformative journey across the galaxy to save everything she has ever known.
Five months after the events of The Undetectables, business is booming – but finding cases that call for magical forensic investigators is not. So when Diana's ex, Taylor, asks them to solve a murder – her own – Diana, Mallory and Cornelia can't say no.
Called to investigate the set of Undead Complex, Diana re-enters the world of TV-show prop making – even in death, the show must go on. Even the appearance of a genuine-article Francine Leon dollhouse can't make up for the fact she's being pulled down a path of crime-solving she maybe doesn't want to walk forever.
Meanwhile, Theodore's coming apart at the seams – literally – in the aftermath of their last case, and Mallory is running out of ways to help him. Especially as he seems to be keeping secrets from her.
As the clues – and the bodies – keep piling up, each one making less and less sense, The Undetectables find themselves in a new race against the clock to find out what, exactly, the killer is up to – before they strike again...
