Book 1 in Juliet Jacka's fabulous new chapter-book series about Frankie Potts, amateur detective, her clever dog named Sparkplug, her formidable and secretly tattooed grandma, strange trails of ants, and a circus that holds the key to all these mysteries...

Book 1 in Juliet Jacka's addictive new Frankie Potts series for readers ages 7–10.
Meet Frankie Potts, the village of Tring's number one girl detective. She has flaming red hair, a questioning mind and an addiction to gobstoppers. And she is REALLY good at solving mysteries.
When Frankie is adopted by a dog at the window of her favourite sweetshop, there's detecting to be done.
The dog, Sparkplug, is adorable. Even Frankie's formidable Grandma M goes all soft and goopy in his presence. Sparkplug can ride a skateboard like a pro, high-five, dance on his hind legs and sniff out a mystery two houses away. He's the ideal dog for a detective. Sparkplug wants to stay with Frankie, and Frankie would dearly love to keep him — but where is he from?
There are other mysteries to solve, and they all seem to be linked: trails of ants; Grandma M's odd behaviour; her secret tattoo . . . What? When and WHY did cardy-wearing Grandma get a tattoo?
A circus has just arrived in the village — it seems a good place to start looking for clues. But first, Frankie will have to get Sparkplug past Tring Dog Control and her arch-enemy, Ralph Peter-McGee.


This is a fun series with a great title character, delinquent archenemies and endless mysteries to solve. Not just for girls.

Laura Hewson, Otago Daily Times

Frankie is a very relatable character, a not-girly girl who kicks ass when she has to, and has the best dog in the world to help her ... Phoebe Morris adds some great touches with her page and small character illustrations.

Sarah Forster, Booksellers NZ

Not too difficult for a good six year-old reader, not too condescending for ten year-olds, and with the universal appeal of being both intriguing and funny.

John McIntyre, Nine to Noon, RNZ National
