Bad Machinery Vol. 6

Published 27 November 2018
School is out for summer, and for the Tackleford mystery team, that means lazy days, balmy evenings, and... creeping existential dread that threatens the whole city. With half the team gallivanting off to exotic locales (like Aunty Kath's in Margate), can Linton, Jack, and Lottie solve this season's most dire case?

The Case of the Unwelcome Visitor, the sixth book in John Allison's award-winning Bad Machinery series, pits our young heroes against the terrors of the unfamiliar and unknown. Lottie's mum and sister have both fallen in love (thanks to the internet), Linton is determined to save his father from the soul-sucking responsibility of a promotion, and why is Jack working at the local paper with team nemesis (and hot-shot reporter) Erin Winters? Isn't print meant to be dead?

Could the link between these tangled threads be The Night Creeper, who prowls Tackleford's streets and leaves people in the hospital with a blank stare and a terrible smile on their face?

From the bestselling author of Giant Days comes the final pocket-sized volume in his beloved Bad Machinery series!


The mystery-solving teens of Tackleford are finding out that not every summer is a perfect one. Charlotte and Shauna, once inseparable, are decidedly on the outs. Mildred bounces between the formerly best friends while trying to save up money for a car. Amy’s rent at the antique store gets tripled, casting doubt on the future of her career. Meanwhile, the boys are channeling their energies into finding love down by the river, with only Jack’s acoustic guitar between them and “romance.” But tragedy strikes when they find that a developer has started building a huge condominium in their favorite swim spot. Unable to get a moment’s peace at home, Charlotte has no choice but to force her way into an internship at the local newspaper, unleashing her brand of maverick sleuthing on... blood pouring out of public art? Strange ooze coming up out of the ground? Shifty doings at the Chamber of Commerce? Classic Tackleford!


The Case of the Severed Alliance pits our favorite crew against the changing tide of time itself as friendships and romantic bonds are tested, and the inexorable wave of gentrification remakes Tackleford itself. Summer is just beginning... but it feels like The End for our heroes? That’s because it is the end: of Bad Machinery!
