Girl with something of value from the east (5)
I believe the answer is:
tessa
'girl' is the definition.
'something of value from the east' is the wordplay.
'something of value' becomes 'asset' (I've seen this before).
'from the east' is a reversal indicator (on a map from right to left).
'asset' reversed gives 'TESSA'.
'with' is the link.
(Other definitions for tessa that I've seen before include "Woman" , "Tax-exempt special savings account" , "Girl's name; former savings account" , "Girl" , "Girl's name, forerunner of ISA" .)
