One clue into the next
Try this. Ana, Ben and Cai own a cat, a dog and a fish. Ben does not have the cat. Cai has the fish. Who has the dog?
Cai has the fish, so neither Ana nor Ben has it. Ben does not have the cat and does not have the fish, so Ben has the dog. Each fact made the next one possible.
In the puzzle above, who has the cat?
