Cross Fire

This is an okay book written by James Patterson. Detective Alex Cross and Bree's wedding plans are put on hold when Alex is called to the scene of the perfectly executed assassination of two of Washington D.C.'s most corrupt: a dirty congressman and an underhanded lobbyist. Next, the elusive gunman begins picking off other crooked insiders, sparking a blaze of theories. The case explodes, and the FBI assigns Agent Max Siegel to the investigation. As Alex and Siegel battle over jurisdiction, the murders continue. It becomes clear that the killings are the work of a professional who has detailed knowledge of his victims' movements – information that only a Washington insider could possess.

This is the seventeenth book in the Alex Cross series.
