The Caper of the Crown Jewels: England

Secret Agent Jack Stalwart #4

by Elizabeth Singer Hunt

In The Caper of the Crown Jewels , Jack is summoned to solve a matter of grave national the theft of the Crown Jewels of the British Empire from the Tower of London. Arriving on the scene, he is greeted by a traditional Tower guard- a Yeoman Warder (or Beefeater)- who explains what's The Imperial State Crown, the Sovereign's Orb, and the Sovereign's Scepter with the cross containing the finest-cut diamond in the world, the Star of Africa. Jack identifies Ivan the Incredible and his assistant, Jazz, as the thieves immediately--but puzzling out how they did it is stickier. The famous Tower has the most advanced security in the world, and even using his impressive gadgets (the Encryption notebook, Heli-Spacer, Rock Corer, and Rope Tornado) Jack is flummoxed by how the jewels were spirited out. However, Jack can conjure up more than gadgets--he foils the evil magicians with some powerful mojo of his own, dispels an invisibility enchantment, and narrowly avoids the executioner's block before restoring the jewels to the crown and earning the gratitude of the Queen herself!

For any of you that have 7-9 year old boys, these are great! They are educational, fun, suspenseful and just great. I enjoy reading them as much as Ty does.

The book is very good and you are going to find some jewels that are stolen but they are not really stolen.

It was a very quick book. It was about a secret agent jack who went to search the jewels after it went missing which was taken by a magician

My second grader is still enjoying these, but I've lost interest. It's your typical mystery, where basically the same thing happens each time. Granted, there are different gadgets which is cool. This one also didn't talk about his brother at all. He even got to ask the queen of England for a favor, and I thought surely he's going to ask for her help to find his brother, but... nope HOMEWORK. Seriously, Jack!

This series is one of the few my son will stay quiet to follow. It is a great bedtime activity.
