Not going straight, like a Victorian pickpocket? (6)
I believe the answer is:
twisty
I believe this is a double definition.
'not going straight' is the first definition.
(not going in a straight line)
'like a victorian pickpocket?' is the second definition.
(like Oliver Twist)
(Other definitions for twisty that I've seen before include "Sinuous" , "Windy" , "Bendy, curly" , "Convoluted" , "requiring one to take turns" .)
