A rich star, so calm, spoiling Dickens story (1,9,5)
I believe the answer is:
a christmas carol
'dickens story' is the definition.
(Charles Dickens novella)
'a rich star so calm spoiling' is the wordplay.
'spoiling' indicates anagramming the letters.
'rich'+'star'+'so'+'calm'='richstarsocalm'
'richstarsocalm' with letters rearranged gives 'christmascarol'.
'a'+'christmascarol'='A CHRISTMAS CAROL'
(Other definitions for a christmas carol that I've seen before include "Scrooge's tale" , "novel" , "Seasonal song" , "haunting story for 8 [EBENEZER SCROOGE]" , "Classic book" .)
