Page 23 of Digital Fortress by Dan Brown mentioned this,
Their courtship was slow and romantic — stolen escapes whenever their schedules permitted...?
I would like to know what is the meaning of "stolen escapes"?
Aside from the obvious meaning of taking someone else's property without their permission, to steal can also mean doing something surreptitiously.
surreptitiously: In a way that attempts to avoid notice or attention; secretively.
In this case, the couple surreptitiously escapes from their surroundings to spend time together.
