Devious spy touring the States with Tom (5)
I believe the answer is:
pussy
'tom' is the definition.
(thesaurus)
'devious spy touring the states' is the wordplay.
'devious' indicates an anagram.
'touring' indicates putting letters inside (touring can mean going round).
'the states' becomes 'US' (abbreviation for the United States).
'spy' anagrammed gives 'psy'.
'psy' placed around 'us' is 'PUSSY'.
'with' is the link.
(Other definitions for pussy that I've seen before include "Catkin tree" , "Cat (colloq.)" , "Water down" , "chap thought to be weak" , "Kitten" .)
