Second Sister

Gossip. Rumour. Revenge.
Wun Wah Tower. Kwun Tong district, Hong Kong.

When Siu-Man jumped from her window on the twenty-second floor, everyone assumed it was suicide. But Sui-Man''s sister, Nga-Yee, a quiet and unassuming librarian, is determined to prove it was murder. The police aren''t interested in re-opening a solved case so she contacts a man known only as N. a hacker, and an expert in cybersecurity and manipulating human behaviour.

What follows is a cat-and-mouse game through the vibrant city of Hong Kong. The pair''s investigation takes them from creepy commuter-train gropers to Siu-Man''s gossipy friends to the dark corners of the city''s digital underground where online bullies, sexual predators and shady tech businesses stalk their prey...
