pwfm PI Brain Twister

The Ransom: Answer

This is a true story which happened in Taiwan.

When the rich man reached the phone booth he found a carrier pigeon in a cage. It had a message attached telling the man to put the diamond in a small bag which was around the pigeon's neck and to release the bird.

When the man did this the police were powerless to follow the bird as it returned across the city to its owner.
