USES
We use the past simple if we give past events in the order in which they occured. However, when we look back from a certain time in the past to tell what had happened before, we use the past perfect. //Example: //The police **arrested ** the man because he **had robbed ** a bank.

The past perfect indicates that the action happened before another one in the past simple.
