You can see divine vengeance going on in this story because of what happens to the Adams twins at the end.

The early parts of this story show us that one of the Adams twins is clearly guilty of murder.  The problem is that this twin is going to escape punishment from human beings because of the fact that the two of them are identical.  Witnesses have no idea which of them committed the crime and so neither will be found guilty.

But (you can argue) God is not going to allow this to happen.  After the twins escape human justice, one of them ends up being killed by a bus.  We are not told exactly how it happens, but that doesn't matter.  The twins escaped human justice but, you can argue, they could not escape God's revenge, His divine vengeance.
