Tanner, maybe in Spain, lies cooking (5)
I believe the answer is:
elsie
'tanner maybe' is the definition.
I can't tell whether this defines the answer.
'spain lies cooking' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'cooking' indicates an anagram (cook can mean to falsify or distort).
'lies' with letters rearranged gives 'lsie'.
'e'+'lsie'='ELSIE'
'in' is the link.
Can you help me to learn more?
(Other definitions for elsie that I've seen before include "Girl's name" , "Lady" , "woman" , "Name for girl" , "Female name; rhymes with London football team" .)
