I watched this one today and am still trying to figure out. Was the young Irish man chasing the client also one of the robbers? How did he know about the gold? The client, Kathleen, didn't know about the gold being stolen did she? How did it get in that black pot?
The man chasing Kathleen wasn't one of the robbers, he was the son of one of the robbers. I don't know how he found out, but I assume his father told him. Kathleen didn't know that the gold was stolen until the end. I don't know how it got in the black pot, I suppose Kathleen's father burried it like that to correspond with the story that he had made up for Kathleen to make her think she was a leprachaun.
