Murder at Union Station — Margaret Truman

Louis Russo, former mob hit man and government informer, arrives at Union Station in D.C. on the last lap of what will turn out to be his one-way trip from Tel Aviv. Two men meet his train. One is the man who will kill him. The other is Richard Marienthal, a young writer whose forthcoming book is based on Russo's life. Russo was returning to D.C. to help promote Marienthal's book, which contains information that may expose not only organized crime but also a top-secret assignment abroad that Russo once masterminded for a very-high-profile Capitol Hill client. As news of Russo's murder rockets from the MPD to the FBI and the CIA, from Congress to the West Wing, the final chapter of his story begins its rapid-fire unfolding.
