The Case of the Exploding Loo

Quirky twelve year old Noelle (Know-All) Hawkins may be one of the brightest girls in her class but even she can't explain how her dad, wacky scientist Big Brain Brian, spontaneously combusted while sitting in a portaloo. It's true that he was working on a new top secret Brain Ray machine and was on the point of a great break-through when he vanished - could this have had something to do with his disappearance? Know-All is sure all is not as it seems and with the help of her sister Holly she is determined to find out what really happened to her dad!
