The Berkeley Square (1998) mini-series is great. I strongly recommend it for those interested in costume drama - you will have plenty of it. The story takes place in 1902. Most of the characters are quite interesting and the very good actors helped making them even more interesting. I read somewhere that the mini-series has 10 episodes. I watched a copy available in the YouTube where at the top of the 10th episode there is a sentence informing that is the last. However, the 10th episode I watched seems quite incomplete, considering it is the last. At the end of the 10th episode there are still too loose ends to be sorted out yet - to end a good and entertaining story like that is not very fair.
