Codename Poltergeist: Some call him a ghost by William Joel

The President of the United States, cabinet members, and the CIA covertly enter into an agreement with the Palestinians to remove certain key Israeli government figures in a plan to enable the United States to claim that they engineered peace in the Middle East and gain the favor of Arabic countries. Sentinel, a group of angelic-type beings who monitor the Earth, are very concerned that the United States could be igniting a major conflict if the Israelis learn of the plan and retaliate. The CIA tried to eliminate their most efficient and deadly agent, James Halyard, Codename Poltergeist, believing Halyard was a possible threat to their plans. They failed, but killed Halyard’s beloved wife, Karen, in the process. Sentinel rescues Halyard, heals him, and gives Halyard the option of becoming an agent for their purposes with highly augmented mental and physical abilities. Halyard truly becomes Poltergeist and is sent to unravel and thwart the conspiracy with the Palestinians.
