I liked it. They find a monkey in the Washington monument and the owner has trained the monkey whenever it sees the word washington it will punch at the o. They find the monkey at the monument and they find a hole in the O and at the end they have a party to see who owns the monkey. And the monkey goes to a lady that sells maps and books about Washington.

I liked it. Someone's stealing something from a memorial stone in the Washington Monument that are worth lots of money.
J PBK R Series: Capital Mysteries Facts are woven into the story.
This story, part of Ron Roy's Capital Mysteries series is great! I loved reading about different places in D.C. and working to solve a mystery in the area was really fun!

The next day, they discover a monkey in the monument during a tour. KC and Marshall set off on a wild adventure to solve a 100-year-old mystery that involves a jewel thief, long-lost diamond

Recommends it for: parents reading with their children
This is an interesting mystery in the Capital Mysteries series, one that is far less dangerous and creepy than the others so far. KC and Marshall visit the Washington Monument and the National Zoo, adding a few more places to our to-see list now that we live in the area. Our girls have really enjoyed the books in this series.
KC and Marshall are friends; one night, while sleeping on the lawn of the White House (the US President is KC's new stepfather), they see twinkling lights in the top level of the Washington Monument. They decided to investigate and then solve the mystery!

Mystery at the Washington Monument by Ron Roy is a great mystery that leaves you thinking about the suspect.It also has cool facts I did not know about.I recommend this book to readers who like mysteries,facts, and politics.
It's funny how they find a monkey in the Washington Monument and they name him Washington. He is very smart and helps them solve the mystery. I really liked him.
Its about how KC and Marshall sees a light in the Washington Monument so they check it out and sees there is a monkey inside and the O for Washington is black .
when kc and mitchell sleep out at night they see lights flickering at the monument and they find a monkey in the building and they come upon theifs and jewel robber.

How big problems!! I think this series' mysteries almost of all are serious problems. However,
This book gets five stars because it's a mystery and it has a monkey in it!
