The Mysteries of Love

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. POK’s aunt KING CHI would like to match him up with a girl but the girl’s background does not really meet the expectations of his parents KING YIN and TSEUNG WAI-CHU. To find out why KEUNG did not hear the shots, HANG and LAI go to consult POK at his laboratory. POK agrees to offer help and has a site visit with them.

Knowing that POK only sees the matter as a fun game to play, LAI gets a little irritated as she will have to rely on his findings and analyses to prove her innocence. POK conducts an onsite investigation, during which he seems to be quite interested in a bundle of electric wires which run through the property office. Inspired by a series of incidents, POK can finally solve the intriguing puzzle. LAI treats POK to dinner at a famous Chinese restaurant, after which they go back home individually. On her way to the MTR station, LAI spots POK eating spaghetti inside a western restaurant. The murderer is finally arrested and HANG offers to treat his staff to a celebration supper……

It is not until this point that she comes to realize that POK is an internationally renowned physicist. While watching a football match on TV, HANG gets a call from a taxi driver, who is taking KA’s Brazilian friend RACHEL to his home. HANG is so captivated by RACHEL’s beauty and vivacity.

Curious to know whether MAN can really see the dead, LAI and POK go to Lantau Island to look for a Taoist priest. On their way back, the pair get lost amid heavy rain. In the confusion, LAI trips and twists her ankle. Due to the geographical isolation of the area, they get very poor mobile reception and can hardly seek help by phone. POK takes LAI to a pavilion nearby so that she can have a rest. The following day, POK is shocked to discover that LAI has fallen unconscious due to the serious inflammation of her hand wound……

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. HEI attends an admission interview with an elite school. Although he has made quite an impression on the principal, he is not selected in the end because of his parents’ poor performance. LEUNG finally manages to convince LAI to consult POK for him, although POK has turned him down already some time earlier. A conference has been postponed, so POK can find time to help LEUNG. He suggests conducting a series of experiments to collect more data, but would need an assistant to help with the process. LEUNG is not available for the tests, so LAI offers to be POK’s assistant on the experiment day. HANG and his team suppose they have arrested the prime suspect for the acid attack, but their guess turns out to be all wrong. POK manages to prove LEUNG’s innocence with his expert analysis……

The scientific journal allows POK a one-month grace period to prove his theory. Due to the limited time available, POK has to choose two from the four test methods for his experiments.

She asks POK how he fell in love with her, and POK explains that it is all about the influence of phenylalanine. A badly burnt body is found in Kam Tin and the victim is an active gang member called KAM TAI-PANG. LAI and PAK-CHU try to gather more background information about PANG from the Anti-triad Unit, from which they learn that PANG used to be very close with a hairdresser named KONG YIU-CHO. Based on the data of PANG’s Octopus smart card and credit card, the police have worked out the approximate time of the murder. CHO was watching a football match at a pub when PANG was reportedly killed, which serves as a very strong alibi for the guy. HEI gets bullied by his classmate……

Keen to prove HEI’s innocence, LEUNG dashes around the park to look for witnesses.

The TSUs and the KINGs meet at the Emergency Room but this first encounter between the two families turns out to be a total disaster. CHI asks LAI out for tea.
