The Clubhouse Mystery

Cass and her best friends, Lex and Nicholas, are the Bubble Street Gang! They investigate crimes, solve mysteries and have brilliant adventures. Theyve 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 Gangs clubhouse. Lexs granny suggests the perfect spot at the back of Mr McCalls 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 theyre 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.
