Peril in the Palace

While visiting Mr. Whittaker, Patrick and Beth find a letter requesting a golden tablet from China. The cousins visit Marco Polo, who is 21 years old and on his way to meet Kublai Khan in 1275. The Khan is easily impressed by the Chinese magicians in his court, but Patrick and Marco Polo set out to show that it is science, not magic, behind their tricks. Upon realizing that Patrick and Beth have rare knowledge, the Khan tries to keep them with him forever.
During their stay in China, the cousins meet Ollie, an 11-year-old boy who has been sending them notes about Albert. The three children win the favor of the Khan's wife, and she helps them escape with a golden tablet that will guarantee them safe passage out of China. When they return home, they find out that Mr. Whittaker has met the mysterious Albert on a previous Imagination Station visit.
