30a Bold sort of artist failing to get going after dawn (10).
This one must be 'adventurer' but I'm struggling to parse the back end. I can see that 'dawn' will be 'advent' and the artist may be Turner but I'm failing to get 'failing to get'! (Or it may be failing to get going.). How does that represent the loss of an 'n'? Or maybe I'm way off target.
