No more letters after this bugle call? (4,4)
I believe the answer is:
last post
'this bugle call?' is the definition.
(I've seen this before)
'no more letters' is the wordplay.
'no more' becomes 'last' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'letters' becomes 'post' (letters in the mail or post).
'last'+'post'='LAST POST'
'after' is the link.
Can you help me to learn more?
(Other definitions for last post that I've seen before include "Bugle call at night or at funeral" , "for mourning people?" , "Final bugle call" , "notes we hear on Armistice Day" , "Bugle call for sunset or funeral" .)
