Question scoundrel raised about kilo in bag (8)
I believe the answer is:
rucksack
'bag' is the definition.
(rucksack is a kind of bag)
'question scoundrel raised about kilo' is the wordplay.
'question' becomes 'ask'.
'scoundrel' becomes 'cur' (I've seen this before).
'raised' says the letters should be written backwards.
'about' becomes 'c' (abbreviation for 'circa').
'kilo' becomes 'k' (phonetic alphabet: alpha, bravo, charlie etc.).
'ask'+'cur'='askcur'
'askcur' in reverse letter order is 'rucksa'.
'rucksa'+'c'+'k'='RUCKSACK'
'in' is the link.
(Other definitions for rucksack that I've seen before include "Hiker often carries one on back" , "Back carrier" , "Trekker's baggage" , "part of hiker's gear" , "shoulder-bag" .)
