Time Bomb - Jonathan Kellerman

This is a secondhand book. It has been read. It is not new. Please note that the picture differs from the version I am selling.

The cheerful chaos of a California schoolyard is shattered one autumn day by gunfire. No children are hurt, but a sniper is shot down - and psychologist Dr Alex Delaware is called in to help the kids cope with the trauma. Then comes another stunning surprise: the identity of the sniper. And Delaware is intrigued by the chance to explore intimately the forces that created such a twisted personality. But as he becomes more deeply involved, he discovers an ever-widening net of malice has been cast - one that reaches far beyond the school compound, and which may already have claimed innocent lives... TIME BOMB is a masterpiece of psychological suspense which shocks...and shocks again
