Cass and her best friends, Lex and Nicholas, are the Bubble Street Gang! They investigate crimes, solve mysteries and have brilliant adventures. They’ve even got their own secret clubhouse.

After the annoying baby twins demolish the fort Cass has built in the sitting room, she has the great idea of building a proper fort – outdoors – that can be the Bubble Street Gang’s clubhouse. Lex’s granny suggests the perfect spot at the back of Mr McCall’s field and Cass and the gang get to work.

The gang settle in quickly and begin planning their next adventure, when they realise someone is using the clubhouse when they’re not there. Stuff moves around, cookie crumbs are left behind and the door is left open. Join Cass and the Bubble Street Gang as they investigate The Clubhouse Mystery.

InTouch Magazine

if they liked The Clockwork Sparrow by Katherine Woodfine they’ll love The Clubhouse Mystery by Erika McGann


a fun story filled with generous grannies, truth bending, and friendship … it's a feel good read full of nostalgia of my own childhood clubhouse

Nayu’s Reading Corner

Erika McGann’s new series is as lively and quick-witted as its central character Cass Okara, founder of the Bubble Street Gang … Cass is exactly the kind of person you’d want leading your gang or as a friend. She has the best ideas, is very funny indeed and never lets anything get her down. This is a hugely entertaining read, full of the kind of adventure that all children could see themselves having, and featuring a great cast of interesting characters.  Nice to see too that it’s not just youngsters who get up to mischief with their friends … There’s a great deal of fun and action packed into a short extent, and the chatty, direct voice McGann gives Cass keeps the pages turning nicely.  Illustrations by Vince Reid add to the appeal’

Books for Keeps

Cass is a real force of nature, lively, impulsive, never short of ideas or the nerve and determination to make them happen. The adventures she gets up to with Nicholas and Lex make great reading, and there’s a special role too for Lex’s equally enterprising granny; as much fun as having your own gang and clubhouse

Perfect for younger readers who are confidently reading alone, this traditional-style mystery story is great fun, enhanced by the lively illustrative material
