This is one of the best of the series, even though Annette Andre is missing. She is replaced here by Judith Arthy who plays her sister in the series. An absolute landmark show of the sixties/early 1970 which was ahead of its time. I am amazed that only 2 series were made, given the excellent chemistry between the regular actors. Also interesting in some of the shows to get a glimpse of what London was like in the 1960s. Highly recommended.
