The Mysteries of Love

The story begins in the early 20th century, when policeman Sergeant TSU teams up with comprador Mr. KING in the arrest of a thief in Hong Kong.

After a thorough investigation, HANG and his team discover that the prime suspect CHEUNG WAH-CHIU was actively involved in the electioneering campaign for KEUNG years ago during the District Council Election, which makes them believe that KEUNG is perhaps trying to return the favor by providing CHIU with an alibi.

LAI is questioned by HANG and MAN PAK-CHU following the sudden disappearance of the fingerprints.

Someone warns on the Internet that the Hong Kong Convention and Exhibition Centre will be bombed real soon.

Accompanied by HANG and his staff, POK and a team of research assistants have arrived with a full set of equipment to carry out a thorough investigation at the reportedly haunted apartment.

LAI goes out for dinner with ON and his family, during which an acid-filled bottle suddenly falls onto the street and injures a number of pedestrians.
