In The Lies of Locke Lamora, what title is Locke known by in the criminal world?

The story behind the answer

In Scott Lynch’s The Lies of Locke Lamora, Locke earns the underworld legend “The Thorn of Camorr,” an elusive master thief whose audacious cons prick the city’s nobility and leave them bleeding pride. The title anchors him to the novel’s setting—Camorr, a Venice-like city of canals and Elderglass—while “thorn” captures how his schemes constantly irritate the powerful.

The other options are red herrings: Emberlain is another city in the series (and the teased title of a later book, The Thorn of Emberlain), and “the Marrows/Rose” aren’t his monikers. Memory tip: the first book is set in Camorr, and Locke is the constant prick in its side—the Thorn of Camorr.
