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?

filled with fun, laughs and a great mystery (or two) to solve, the third in this series is even better than the rest. An engaging story, Diary Detectives is easy to read, but still challenging as it pulls the reader along through these children’s world at a pitch-perfect, absorbing rate. You feel as if you know these people. Cass and her friends are realistically drawn and the adults in the story are seen through real children’s eyes. While there are loads of wacky episodes, there is also a strong sense of realistic, logical thought and good detective work as they work their way through another mystery. It has that sense of childhood wonder and adventure that makes it a joy to read at any age. The drawings are whimsical and lively; adding life, imagery and a strong feeling of time and place that allows the characters and the story to jump off the page. So funny, sassy and warm, you'll want to join in!
