Sent:

A wicked man lived near a monastery. He believed [unfoundedly] that
the monks had great treasure, and covetted it. The wicked man became a
policeman. One day, he accosted a monk who was returning to the
monastery. "Give me your key," he said. "I want to search the
monastery for any criminals who may be hiding there." 

The monk said, "I have no key."

The wicked policeman flew into a rage [lit. hurled himself into a
rage], but the monk went into the monastery through the open door.
