Tips:
You are about to meet Frederick Abberline(a policeman), who helps us Conquering the WhiteChapel and also eliminating the Thugs. After the cutscene, he will offer you with a mission where you need to Kidnap a Thug and bring him back to Abberline. If you do it right he will continue with the further agreements. The side objective here is not to kill the target instead bring him back alive.
Tips:
