Travel around with a rascal (6)
I believe the answer is:
varlet
'rascal' is the definition.
(I know that rascal can be written as varlet)
'travel around' is the wordplay.
'around' indicates anagramming the letters.
'travel' is an anagram of 'VARLET'.
'with a' acts as a link.
(Other definitions for varlet that I've seen before include "Travel around with old rogue" , "Travel with old rascal" , "Travel (anag) - rascal (archaic)" , "Aged attendant" .)
