Roger and his girlfriend Claire at a hypnotist's show. The hypnotist very good but he and his assistant criminals.
The hypnotist gave Roger secret commands while he hypnotised.
At night Roger broke into the museum and stole the jewels.
The next morning Inspector Lime and Sergeant Lewis at the museum. Sergeant Lewis very clever but Inspector Lime not.
Roger at the hospital and Sergeant Lewis and Claire there, too. She told the Sergeant about the hypnotist and he knew what had happened.
Later the criminals arrested in Singapore.
The newspaper said Inspector Lime had solved the case so he very happy. Sergeant Lewis not so pleased.
