Following this Walter and Peter investigate a Chinese merchant ship, and onboard they find passengers who have died as the result of parasites bursting from within their bodies. Upon further investigation it turns out that these parasitic worms secrete opium. Walter is bitten by one of the worms but maintains he is fine. Walter soon finds Ming Che and does some probing. Shortly after he is kidnapped by the Triads but subsequently released. Peter heads straight to Ming Che’s address but finds himself strapped down with a worm forced into his mouth.
