Malice in the Palace by Jules White

5.60

Set in a desert land where the stooges run a restaurant, the boys set out to recover the stolen Rootin Tootin diamond after they learn from the thieves that the Emir of Shmo has absconded with the contraband jewel. They journey to the stronghold of Shmo where they disguise as Santa Clauses and scare the ruler into giving them the diamond.
