Narrated what turned out to be an order endorsing capital punishment (5,7)
I believe the answer is:
death warrant
'be an order endorsing capital punishment' is the definition.
I can't tell whether this defines the answer.
'narrated what turned out' is the wordplay.
'turned out' indicates an anagram.
'narrated'+'what'='narratedwhat'
'narratedwhat' is an anagram of 'DEATH-WARRANT'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for death warrant that I've seen before include "Execution order" , "order to kill" .)
