Trash

This book is about two poor boys called Raphael and Gardo who are like brothers. They have no parents and earn a living by looking through the trash. One day they find a bag that has a wallet and a map. Later that night, some police come to their home. They lie to the police and say that they didn't find anything. Then they hide the bag with their friend Rat (Jun-Jun) who has no parents or family and lives with the rats. Raphael is then taken to a Police station where he is interrogated. They ask if he had found anything and he denies anything which angers them so they hang him out the window and let him fall. Fortunately, Raph survives the fall. 

Then Rat recognizes a key that was in the bag as a locker key. They go to the train station where the locker is and use the key to open it. In there they find a letter. It is addressed to Gabriel Olondriz from Jose Angelico.
