Doctor Finlay

This is an excellent series. The actors are well cast and do a great job. The scripts are well written, although the episode endings are occasionally unfinished or hard to understand. The one problem I have with the series is that David Rintoul sometimes plays Doctor Finlay as stiffly as he played Mr. Darcy. He really needs to loosen up a bit. I have a question. Does anyone out there know where I can get a copy of the last episode in season four called "Doctor Finlay Snowbound"? I think it may have been broadcast at a later date that year as a special. It's not included in "Doctor Finlay Days Of Grace" which is the last series available for purchase.
