Our hearts go out to the residents of Nonnatus House this week.

They are fearing for one of their own as Barbara fights for her life in hospital after being diagnosed with meningitis.

While Tom is desperate to stay by her side, Phyllis is bustling around re-organising rotas and supporting Tom while trying to keep a lid on her own worries.

Meanwhile, homesick Lucille makes some new friends, and Dr Turner has a tough case on his hands when, at a local reform school, he comes into contact with a troubled teenage car thief who is being kept apart from his pregnant young wife.
