Ordering a suspect into river (3,6)
I believe the answer is:
rio grande
'river' is the definition.
(Rio Grande is an example)
'ordering a suspect' is the wordplay.
'suspect' indicates anagramming the letters.
'ordering'+'a'='orderinga'
'orderinga' anagrammed gives 'RIO GRANDE'.
'into' is the link.
(Other definitions for rio grande that I've seen before include "Mexico-USA border" , "running water" , "banker" , "Great river bordering USA and Mexico" , "Waterway rising in Colorado" .)
