"Final breath after debt's bill accepts a tragedy" (5)
(it might be difficult, i've literally never done this before)
Spoilers!
It's a double definition! "Final breath" and "tragedy" meaning "death"
The solution is to:
replace the 'b' in 'debt' with 'a'
(debt's bill [b] accepts a)
and append ('after') h
(final breath = final letter of breath = h)
