Tom Barnaby runs into his old friend (and, it would appear, old flame) Dr. Jane Moore when he has to investigate a death which at first appears to be a suicide and then begins to look more and more like a murder. Dr. Moore is a caring professional who is a widow raising a son and two daughters alone but also finds the time to help people with problems with her 'care in the community' approach.
When more deaths occur, Tom is completely at a loss to know who is responsible when Dr. Moore's patients and a local band leader all meet their deaths. When Tom himself almost becomes a victim, he realises just in time that a certain three young people are not what they appear to be. The phrase 'have you checked the children' could not be more appropriate than in this episode except in this case, watch out for those kids!
Fantastic viewing, even a little scary in places, which makes it even better.
