The case of the borrowed things
Three neighbors each borrowed one thing from the Gold Brothers’ garage: a ladder, a kite and a bucket. Who took what?
Clues
- The gardener needed something to carry water.
- The painter didn’t take the kite.
Tap a square once to cross it out, twice to mark a match, and a third time to clear it. Every case in the book works the same way: cross out what can’t be true.
Did you know? People in China were flying kites more than 2,000 years ago.
Who took what?
Case closed!The gardener took the bucket, the painter took the ladder, and the mail carrier took the kite.
Stuck? Show the answer
The gardener took the bucket (clue 1). The painter didn’t take the kite, so the painter took the ladder. That leaves the kite for the mail carrier.
