Summed up as a tale told badly (8)
I believe the answer is:
totalled
'summed up' is the definition.
'totalled' can be an answer for 'summed' (I've seen this before). I'm not certain of the 'up' bit.
'a tale told badly' is the wordplay.
'badly' indicates an anagram (letters in the wrong order).
'tale'+'told'='taletold'
'taletold' anagrammed gives 'TOTALLED'.
'as' is the link.
Can you help me to learn more?
(Other definitions for totalled that I've seen before include "completely destroyed" , "blown away" , "Determined the sum of" , "came to" , "Summed" .)
