When we visited Poplar for the Christmas special, the whole place was knee-deep in snow.
As this seventh series of Call the Midwife begins, we’re still in 1963 and it’s the coldest winter for 300 years.
The nuns and nurses are still managing to go about their duties – just. Sister Winifred is hoping to take her driving test so she can get around the district. Trixie is attending the delivery of a baby to a former stripper.
And Nurse Crane is tending to a dying Jewish woman who fled the Nazis during the war. There are moving scenes as she fades away, clinging to routines by sitting in bed polishing candlesticks. Her home is facing demolition so everyone rallies round to make her final hours as bearable as possible.
With Cynthia, Patsy and Delia gone, and Barbara living with husband Tom, what Nonnatus House needs desperately is a new recruit.
Enter Lucille Anderson (Leonie Elliott), who is from Jamaica and has graduated from nursing school in Taunton. Phyllis is put out she’ll have to share her room (again) – but pleased to have an extra pair of hands.
Call the Midwife is on Sun 8pm BBC1
