Anil realized that his money was stolen the previous night since the notes were wet when he woke up and it had rained the previous night which made it clear that the notes were out in the weather. However, he did not say anything to Hari. Neither did he hand him over to the police. There can be many reasons behind this decision of Anil. One, he was a good man and he knew how difficult it was to live in poverty since he himself made money by fits and starts. His profession (a writer) signifies a sound and mature mind which can differentiate between a criminal at heart and a criminal by circumstances. Since Hari had returned, Anil knew that he had realized his mistake which was, probably, enough for him to learn a lesson in life.

On the contrary, many other people would have taken an opposite decision and would have handed Hari to the police.

The fact that Anil fed Hari meals, taught him, did not say anything to him despite knowing that he made some money when he went to the market for some purchases, and did not hand him over to the police make him very different from the other people.
