SHADOW by Karin Alvtegen

As darkness falls on 10 May 1975, a little boy waits alone on the steps of an amusement park.  The park is about to close and everyone is leaving, except this child.  He continues to wait there, not daring to move.  He has been told to stay right where he is.

Only no one is coming back for him.

Why has he been abandoned, with only the briefest of notes to whoever finds him?. And what connection do the events of this day have to the death of Gerda Persson thirty years later - a woman who leaves few clues to her life, apart from a freezer full of books?

Soft cover, good condition.
