This episode was wonderful and eye opening, it was eye-opening in the sense that in the auction at Old man Catesby's farm, really honed down on the dark-side of the antique trade with the tag swapping fiasco with the old Welsh dresser. This showed the depths dealers go to get that one step ahead of the competition, and if it weren't for the charm of Lovejoy and Tinker we might actually loath their antics, but instead we enjoy it and cheer them on.
The tax collector was a nice touch I think , as it show us that it is more than petty thugs (as shown in the previous episode) that Lovejoy is trying to avoid, as I imagine some of the taxes you would have to pay on certain purchases to be quite crippling.
The only grumble about the episode, and is a small grumble, is that half way through the episode, Lovejoy travels to London to find a buyer for the Arab head-wear. And to me, I prefer the episode when the episode is solely based in Suffolk/ Norfolk as I believe it is just as important & influential as the characters in the show.
My favourite moment in the episode was the auction at Old man Catesby's farm and the antics that occurred.
