The Footmarks?
One day Kitty and Cat saw footmarks on the clean kitchen floor. At night Kitty and Cat went into the kitchen to investigate. But who would have put them there?
Kitty and Cat got all the shoes and put them against the footmarks. Was it Dad or Mum? No, they would never be so messy.
What if it was Hannah or Elle? No, their feet were too small. Oh, it must have been the new cleaner that came. And they solved the mystery.
