Beefeater, market trader or squealer heading home? (7)
I believe the answer is:
tootsie
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for tootsie that I've seen before include "Foot or toe (childish)" , "A child's foot?" , "Funnily enough, foot" , "Foot (jocular)" , "Foot or toe - I set, too (anag)" .)
