Meet Dorothy Constance Mae Louise, or Dot as she prefers to be called!

Dot loves super-sour apple sherberts, running fast and puzzles - especially if they're fiendishly tricky. And with the help of trusty sidekick, Beans and TOP DOG, McClusky, she is always ready to sniff out a mystery. So when meangirl Laura seems set on sabotaging the school talent show, Dot is determined to find out how, and save the day.
