Degree of difficulty (by standards of this weekly puzzle): hard. A bit of a British feel to this one, with more cross references than usual.
Hozom's comment: Turnabout is Fair Play (but not exalted), in which reversals and their indicators are discussed. Reversals play well with others: they are easy to integrate with other clue types.
