Summary:

He eventually leaves the CIA after several failed assassination attempts are mad on his life. He leaves his card however, in case the need for his expertise should arise.
Now, after 20 apparent suicides with striking coincidences, Jasper is faced with a killer who works in the shadows, and without so much as touching his victims.
