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. 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.
