Hong Kong - The international brokerage house for the exchange of secrets. Somebody was buying some big ones and selling them at a big profit. Then a girl nobody seemed to care about got killed. Somebody cared. Senior Superintendent John Crown of the Royal Hong Kong Police Force. And when he took a hand, Chang Po his Chinese partner, joined the action.

Macao - Not a part of Crown's Colony. But the bloody and violent trail led there, so that's where Crown and Chang went. In the tracks of a girl who knew too much. Enough to make her another victim - unless she traded her secrets for protection instead of money.
