Three families. Three deaths. One house that never stopped killing.

Feng Hua Wang is called to a luxury apartment in Mid-Levels where three families have died in the same unit over twenty years. The latest victim: a property developer who bought the place at a discount. The police say heart attack. Wang's compass says otherwise.

Yue Lin — ex-Flying Tiger, six years in counter-terrorism — is assigned to protect the building's remaining residents while Wang traces the energy. But someone doesn't want the truth to come out. Someone who knows exactly what Wang is looking for. Someone who's been waiting twenty years for him to walk through that door.

Every house has a history. This one has a body count.
