Escapee died quietly, tragically, beyond the moon's orbit (4,5)
I believe the answer is:
deep space
'beyond the moon's orbit' is the definition.
I can't tell whether this defines the answer.
'escapee died quietly tragically' is the wordplay.
'died' becomes 'd' (abbreviation next to the year of someone's death).
'quietly' becomes 'p' (musical symbol).
'tragically' indicates an anagram (I've seen this in other clues).
'escapee'+'d'+'p'='escapeedp'
'escapeedp' anagrammed gives 'DEEP SPACE'.
Can you help me to learn more?
(Other definitions for deep space that I've seen before include "even devoid of 12 [THIN AIR]" , "Region beyond our atmosphere" , "void" .)
