 Maggie Bolton has discovered that she and her husband are having a baby, and that scares her because they have lost a baby before to cot death. To think things over she goes on a weekend trip with Gina. There has been a series of small fires in Aidensfield. Mostly in garbage cans and haystacks and things like that, but one night a cottage is burning, and Neil Bolton rushes in to save a baby trapped inside the house, when the roof collapses. The baby is saved by his older brother, but Dr. Bolton is not! Greengrass has bought an old railway carriage to use as a holiday cottage for paying guests. His first customers are on their way already, but he does not have the proper licenses. Nor does he need any - or so he thinks.
