This e-mailer knows how to get my attention:

I noticed the same mistake in The Lost Symbol. There are others, too. It probably comes out better on the whole, though, than 24โ€”tunneling under the White House from the Potomac????
At any rate, can you recommend one or two other DC thrillers for me? (Weโ€™re buying The First Assassin for a couple of family members for Christmas!)

Two (other) great Washington thrillers: Shelleyโ€™s Heart by Charles McCarry and Seven Days in May by Fletcher Knebel and Charles W. Bailey II. A great novel of Washington politics: Advise and Consent by Allen Drury.
