Quote from Adrian Monk in Mr. Monk Goes to the Bank
Madge: I don't understand. Adrian Monk: Half a boxful. It's an unusual phrase. Then I remembered. There are six extra large deposit boxes in that vault. But during the robbery, the Russian only opened five. Lieutenant Disher: Well, he ran out of time. He was in a hurry. Adrian Monk: But it wasn't the last one. The one he skipped was in the middle. Box 503. Natalie: The money never left the bank. Adrian Monk: It's brilliant when you think about it. It's the last place anybody would look.
