Overview: SUM and the others wait for HOI as he is being treated at the emergency room. The doctor says HOI’s injury on his right leg has resulted in its lack of strength. YEE, who is on the phone, looks very angry. HONG and HAN want to give her some words of consolation, but SUM asks HONG why he has been going out a lot with a restaurant hostess. WING has come round. SUM and TING visit him. As WING has difficulty in speaking because of his throat injury, SUM instructs him to answer his questions by winking. ANTHRAX has been killed. TING notices that the footprints on his body are very similar to those on the victim of the previous murder case. SUM and the others go to HOI’s house to arrest him. They are surprised to find YIN, who has just woken up, in HOI’s room. Enlightened by TING, SUM sets about to find out more information about HOI’s days in prison from the Correctional Services.
