Thin plot and even a bit of a mystery worked into a story really designed to paint life in Washington, and the things to see there. Two boys and a girl, whose father is elected to Congress, leave Connecticut and descend on Washington, ready for anything. There's a bit of an inside picture of the House of Representatives in action- the White House- the Lincoln Memorial- the Smithsonian- and so on and so on. The children are instrumental in finding a missing veteran son of one of Dad's constituents -- and, oh yes, a buried treasure dating back to the Civil War. But it all seems fairly artificial and contrived. Use with lower and middle teens.
