Book 3 in the Cass and the Bubble Street Gang series! 



Cass, Lex and Nicholas investigate crimes, solve mysteries and have brilliant adventures. They’ve even got their own secret clubhouse. 



Cass is not impressed with the new Residents' Association programme -- suddenly everyone's in Neighbourhood Watch and thinks they're a genius detective. And that’s Cass’s job!! Worse still, there are so many new rules that the kids can't even play on the street anymore. No one stops Cass and the gang from playing games - something will HAVE to be done about the Residents' Association...



But there's also a mystery afoot for the Bubble Street Gang: while helping with a car boot sale, Cass finds a very old diary. The name inside the cover has worn away, but it must belong to somebody in Berbel Street. The diary talks about picking on the drama kids on the bus, and finally about a horrible prank played on them during their end-of-year show. Who does this diary belong to? Can the Bubble Street Gang unmask the wicked writer?
