Foreign soldier reading novel about Rising (9)
I believe the answer is:
Here is my best explanation:
'foreign soldier' is the definition.
'grenadier' can be an answer for 'soldier' (grenadier is a kind of soldier). I am not sure about the 'foreign' bit.
'reading novel about rising' is the subsidiary indication.
'novel' indicates anagramming the letters.
'about rising' becomes 'er' (I am not sure about this - if you are sure you should believe this answer much more).
'reading' is an anagram of 'grenadi'.
(Other definitions for grenadier that I've seen before include "historical bomber", "bomb-thrower", "Guard", "The guard", "African flier", "Infantryman - in red gear (anag)", "Soldier - in red gear (anag)", "Soldier; fish; bird", "A household infantryman" and "Re-reading for the deep-sea fish".)
