One of the immediate challenges for a reader going through books that are set years apart is to find a reference point that makes it clear what has happened in the in between years.
Having gone through 1980 with an alternate character narrative it picks up again this time weaving in the strands of thoughts from John Piggot, a solicitor looking to help with the appeal of the wrongly fitted up child killer from 1974 and Maurice Jobson a senior policeman.
Things start weaving backwards and forwards through time starting to fill in the gaps not just from 1974 but even before that.
The same dreams are there with references to underground kingdoms and wolves but there is from the start a clear indication the story will be told through the latest case of a missing girl.
