Amusement in confusion (6,7)
I believe the answer is:
helter skelter
'in confusion' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for helter skelter that I've seen before include "Slide" , "in disorderly haste" , "haphazard" , "headlong" , "Hurriedly" .)
