Stories about Tom perhaps in French city (7)
I believe the answer is:
limoges
'french city' is the definition.
(I've seen this before)
'stories about tom perhaps' is the wordplay.
'stories' becomes 'lies' (to tell stories can mean to lie).
'about' indicates putting letters inside.
'tom perhaps' becomes 'mog' (I am not sure about this - if you are sure you should believe this answer much more).
'lies' going around 'mog' is 'LIMOGES'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for limoges that I've seen before include "French city known for its porcelain" , "French city noted for enamels and porcelain" , "French commune" , "French porcelain centre" , "foreign city" .)
