I will get a number to follow through danger (5)
I believe the answer is:
peril
'danger' is the definition.
('peril' can be a synonym of 'danger')
'i will get a number to follow through' is the wordplay.
'will get' is a charade indicator (letters next to each other).
'a number' becomes 'l' (L is an example**).
'to follow' is a charade indicator (letters next to each other).
'through' becomes 'per' (I've seen this before).
'i' next to 'l' is 'il'.
'il' after 'per' is 'PERIL'.
(Other definitions for peril that I've seen before include "Hazardous situation" , "Great danger" , "Danger, jeopardy" , "Danger of serious kind" , "Quest" .)
