MURDER ON K STREET—Margaret Truman—The latest in the Capital Crimes seires is an improvement over the past couple. This time Ms. Truman kept me engaged with a story of Senator Lyle Simmons, and his unlikely continuing friendship with college roommate Phillip Rotondi. Senator Simmons and Rotondi go a long way back to and including both having been in love with the same person. As Simmons rose in politics, he became involved with possibly unsavory lobbyists. Simmon’s wife is murdered, his son is President of the lobbying firm, his daughter is distant and his college buddy comes to be a friend and while there, with Mac and Annabelle Smith (Truman’s often heroes) among others manages to discover who killed Mrs. Simmons as well as a couple of others.
