A witty, witchy fantasy murder mystery packed with ancient magic and fiendish puzzles. Mallory, Diana, Cornelia and Theodore are hired to solve a murder on a TV shoot by the victim herself. Perfect for fans of supernatural mysteries and cosy crime by authors such as Ben Aaronovitch, Josiah Bancroft and Tammie Painter.

Five months after they stopped The Whistler, business is booming for the Undetectables. Just not work that requires magical forensic investigators. So when Diana’s ex asks them to solve a murder – her own – Diana, Mallory and Cornelia can’t say no.

Going undercover to investigate the set of the TV show, Undead Complex, Diana returns to her life as a propmaker. But even the appearance of a genuine-article Francine Leon dollhouse leaves her feeling pulled down a path of crime-solving she doesn't want to walk forever.

Meanwhile, Theodore's coming apart at the seams – literally – 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 race against time to find out what, exactly, the killer is up to – before the final cut.
