Sterling's Turkish Adventure is automatic and is part of the main story.
Please Note: This caper is still techincally considered a Sterling caper though it is part of the main story. The wiki chose to put it on the main adventure page and Sterling's main adventure page to simplify things for players.
Players do not initiate the caper, it just automatically happens regardless of what route you are playing. If you are on the Dream of Sterling path, the options will change from giving +relationship points for Sterling and skills, to +Dream of Sterling. There are also noticeable dialogue changes.
