Nice woman when you first meet then you find out she will rob, kill, steal and commit any other crime against you with a second thought; sneaky and dangerous woman
For example a "treacherous bitch" you meet a nice woman at work to later find out she has set people up to be robbed, killed, and the above. She might have changed for you but she will strike again do to the unstable nature of her personality.
