It's all right officer. I'm just waiting for a friend.
Rather a long time between meets, though, it seems to me.
His "Friend" Arrives
Is that you, Jimmy Wells?
Is that you, Bob?
Bless my heart!
The police is patrolling the area. It is rainy and dark. No one is on the streets....
Who is This Man?
You're not Jimmy Wells!
You've been under arrest for ten minutes"Silky Bob"
The officer finds a man who is waiting for his friend to meet him. This is their meet twenty years later. The police questions him to make sure of his alibi.
Bob's Secret Revealed
After the officer leaves, the man waits for his friend. When his friend arrives they walk down the street on the way to a place that Jimmy is going to take him.
Whole Story Uncovered
He's a note I was asked to had you. It is from Patrolman Wells.
On their way, Bob notices that this man is not Jimmy Wells, his friend. He recognizes different parts of his face.
During the last scene, we know that Bob is a robber and Jimmy was the police officer that was patrolling the area earlier. Bob is the man wanted in Chicago when his friend is a police officer.
Man wanted in Chicago
The letter above shows that Jimmy could not arrest his friend so he got another man to do it. He couldn't throw his friend in jail.
Bob:I was at the appointed place on time. When you struck the match to light your cigar I saw it was the face of the man wanted in Chicago. Somehow I couldn't do it myself, so I went around and got a plain clothes man to do the job. JIMMY
