We are more used to Call the Midwife focussing on the beginning of life.
We watch the pregnant mothers of Poplar as they welcome bouncing babies into the world, we fret about childhood illnesses and see new families thrive in the face of adversity.
But the final episode of series three is set to shine a light on the end of life instead.
Call the Midwife's series three finale, which airs on BBC1 this Sunday, will feature an "end of life care" storyline, RadioTimes.com has learned.
The episode, further details of which the BBC are keeping as a surprise for fans and TV critics alike, is set to focus on Chummy and her mother Lady Browne, who we learned in last week's episode had been diagnosed with incurable cancer.
Chummy and her mother have an icy relationship, with last week's episode seeing the pair come to blows over Chummy's life in Poplar.
But tensions are likely to run even higher this week as the midwife is faced with difficult decisions over her mother's death...
Call the Midwife is on Sunday at 8:00pm on BBC1
