Did the wrong course get him shipwrecked? (6)

I believe the answer is:

crusoe

I'm a little stuck... Click here to teach me more about this clue!

'him shipwrecked?' is the definition.
The definition suggests a singular noun which matches the answer.

'did the wrong course' is the wordplay.
'course' anagrams to 'CRUSOE'.
However, I am unsure how the anagram is indicated.

'get' acts as a link.

Can you help me to learn more?

(Other definitions for crusoe that I've seen before include "Shipwreck victim" , "Defoe's hero derived" , "Shipwrecked hero" , "See 9" , "Daniel Defoe's hero" .)

I've seen this clue in the Evening Standard.
