According to HA #130: "This time Europeans are involved with the Turks. An American is tasked with heading to Mecca to rescue an American woman, but runs afoul of an Austrian spy who aims to prevent Arabs from taking control of Mecca from the Turks. Solomon is somehow involved, as this will weaken the Turks if successful. At the end, Solomon decides to shut down his shop and move elsewhere, which makes sense as WWI has ended, along with the threat of the Turks in the Middle East."
