Tessa returned something of value (5)
I believe the answer is:
asset
'something of value' is the definition.
(I've seen this before)
'tessa returned' is the wordplay.
'returned' says the letters should be written backwards.
'tessa' back-to-front is 'ASSET'.
(Other definitions for asset that I've seen before include "Tessa (anag)" , "Useful thing or person" , "Valuable thing" , "One bringing benefit" , "Something useful" .)
