Described as a historical mystery, it has a good deal of police procedural work involved and would interest readers of that genre as well. Set in the 1943 period the story involves a decades old unsolved murder of a little boy which troubles the Detective at the station.
When he gets the go ahead to further investigate from his superior officer, Detective Mason and his constable O'Rourke start a systematic search of all possible clues and come up with missing information, wrong procedures followed and then link up with a stream of other cases across Scotland, Northern Ireland and England with a very similar form of death.
Putting the pieces together and bringing closure to several families was an act of mercy and though justice could not be meted out as the murderer had already died, the story was a good, methodical piece of detection work.
