Rumpole of the Bailey - Season 2 Episode 2 Rumpole and the Case of Identity

With the Christmas season in full swing, Rumpole defends Dave Anstey on the charge of stabbing a sales assistant in an off-license. It seems to be a case of mistaken identity, but why does Dave's boss, on whom his alibi depends, change his story and undermine the defense? Meanwhile, Rumpole's Head of Chambers has an attractive new secretary, and starts spending a lot of time with her behind closed doors... When Guthrie Featherstone is seen gyrating at a disco with the girl from the typing pool, Rumpole means to get to the bottom of it all.
