How to teach a child to sleuth.

Step 1: Get those kids in the middle of mysteries.

There aren't any mysteries on the Internet. Get them out of the house.

Step 2: Encourage creative thought.

Give them a rubrics cube, teach them chess, have them learn the dewy
decibel system, knot tying, Morse code, and juggling.

Step 3: Weapons training.

Nun chucks, pocketknives, pistols, and paint cans can all be used as weapons.

Step 4: Stop crime!
