Description

A witty, witchy fantasy murder mystery packed with ancient magic and fiendish puzzles. When Cornelia's twin sisters are taken by the Wickermere Reaper, Mallory, Diana and Theodore must race against time to uncover the buried secrets of the Broadwicks before it's too late. Perfect for fans of supernatural mysteries and cosy crime by authors such as Ben Aaranovitch, Josiah Bancroft and Tammie Painter.

The summer after the events of The Undead Complex, the unthinkable finally happens - Cornelia's money is running out. Estranged from her family, furious at her parents following recent revelations, the Broadwick heir finds herself living on her own resources for the first time.

Meanwhile two crimes are rocking the Apparent community. The Wrackton Digger is stealing bodies from the cemetery, and a new serial killer - the Wickermere Reaper - has emerged. But when the Reaper snatches their next victims - Cornelia's twin sisters - she must return to her family's home, and seat of the Ghoul Council, to conduct the search.

With their resources split, and a ticking clock on the race to save the twins, The Undetectables must do what they do best - solve the strangest, most well-hidden magical mysteries to save the people they love.

Critic Reviews

Praise for The Undetectables


"A compulsively readable race against the clock to stop a supernatural killer - downright delightful and unapologetically queer."
Polygon.com


"Unputdownable. Grim and caring, twisted and witty, The Undetectables is gripping and charming in equal measure. You won't want to leave Wrackton, while also being really glad you don't live there." Deirdre Sullivan, author of Savage Her Reply


"If you aren't already deep into spooky season then here is the perfect book to get you in the mood."
Irish Examiner


"A fun and breezy Urban fantasy novel that has an interesting take on using magical forensics"
SFBook Reviews


"If you're looking for a mystery that makes you think, mixed with a healthy dose of supernatural, diverse representation and some of the best dialogue I've seen in a long time then [...] The Undetectables is the book for you." Geeking By


"I got so invested in these characters and by the last page I simply did not want to leave them behind. I'll take a hundred more cases that need to be solved by the Wrackton gang, even if I need to commit them myself." Read By Ross


"It feels like if Halloweentown, Charmed and A Good Girl's Guide to Murder had a baby as a group of 20 year olds reunite to find [a] magical serial killer [who] starts targeting their small town." Ace Reader


"An urban fantasy that feels light but has a lot of heart, with a fantabulous cast and oddly adorable glowing beetles, The Undetectables is my new favourite friendship-fantasy. I strongly advise you not to miss out on it!" Every Book a Doorway


"This book was addictive and I found myself unable to put it down! It was impossible for me not to love this group of friends who each bring their own to The Undetectables. Not only do we get a lot of representation in this book but each character is unique and incredibly realistic and relatable." Once More With Reading


"An entertaining, light-hearted mystery novel with an engaging group of characters and a solid sense of worldbuilding ... this could be the auspicious start of a new fan-favourite series."
Set The Tape


"Unapologetically queer and diverse with the perfect vibes for spooky season!" Quinty Narings (NetGalley)
