The Thompson Twins are preteen detectives from Minnesota who have a reputation for being friendly, clever, and good at solving puzzles and mysteries.

When people first meet Tony and Tina, they often ask, “How are you twins? You look nothing alike!” Depending on whose turn it is, Tony or Tina explains about fraternal twins as quickly as they can so they can get to work on the mystery. After all, they were called to solve a mystery not to give a science lesson!

Join Tony and Tina and learn a little something along the way as you investigate and sleuth along with the Thompson Twins. You will choose which clues to follow and which people to question. See if you can find the solution before the Twins do!

The books are a mid-grade (3rd through 6th grade), interactive detective series. Picture a combination of: Encyclopedia Brown, Magic Tree House, and Choose Your Own Adventure.
