THE BOMBINGS FORMED A STRANGE, INEXORABLE PATTERN-

Each explosion came on a rainy night
Each was related to the others
Each struck in a "restricted" area
Each was directed at a leader of a fanatic organization, misnamed "Sons of America"
Each was fatal
And each left no clues!

Without clues, you can catch a killer only one way: at the scene of the crime. But how can you stop a criminal who moves through time and space to murder his victims --- completely and irrevocably --- days before the moment of actual death?
