Suspect death is within recall of heads of some leading Anglican and Roman Catholic churches (10)
I believe the answer is:
cathedrals
'roman catholic churches' is the definition.
'cathedrals' can be an answer for 'churches' (cathedral is a kind of church). I'm not sure about the 'roman catholic' bit.
'suspect death is within recall of heads of some leading anglican' is the wordplay.
'suspect' indicates an anagram.
'is within' is an insertion indicator.
'recall of' says the letters should be written backwards.
'heads of' says to take the initial letters.
'anglican' becomes 'arc' (I can't explain this - if you can you should believe this answer much more).
The first letters of 'some leading' is 'sl'.
'sl'+'arc'='slarc'
'slarc' written backwards gives 'crals'.
'death' anagrammed gives 'athed'.
'athed' put into 'crals' is 'CATHEDRALS'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for cathedrals that I've seen is " religious places".)
