I have to say this was not a good episode. It was more humorous than an investigation taken seriously.
Julie getting caught at the beginning and has to break her cover and stumble into another cover.
The Angel's plan to have the Con Man really marry the owner of Sturgis Galleries and marry into "the family" for good. In other words this will be a marriage he will not be able to leave because of the Mafia ties.
I would have rather seen the Con Man sent to prison.
It seemed as if the writer's in this episode did not give any thought, but rather went a different avenue a made it humorous.
