Prison block where lawyer is keeping close to Laurence Fox (5,3)
I believe the answer is:
death row
'prison' is the definition.
(thesaurus)
'lawyer is keeping close to laurence fox' is the wordplay.
'lawyer' becomes 'da' (abbreviation for District Attorney).
'is keeping' means one lot of letters goes inside another (some letters kept inside).
'close to' suggests the final letters (the close of something is the end).
'fox' becomes 'throw' (synonyms).
The last letter of 'laurence' is 'e'.
'da' enclosing 'e' is 'dea'.
'dea'+'throw'='DEATH ROW'
'block where' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for death row that I've seen before include "In USA, part of prison where condemned criminals are held" , "location of worst offenders" , "Cell block where prisoners await execution" , "Cell block for those due to be executed" , "Place for prisoners awaiting execution" .)
