A Shadow Of Doubt
Follow the man with the pink umbrella. Whenever he turns around, hide behind something, whether it be a wall or a Yankee. Eventually he'll reach a friend. While they're talking, plant a tracking device on their car. When they leave, get in a car and follow the blip on your radar, which updates intermittently. When you reach their hideout, the mission ends.
(Hsin arrives in a Limo)
Hsin: You took your time getting here. Lucky for you, you made it just in time to meet the inbound train. One of those rebellious little pricks is coming in on that train. Follow him. He should be heading for their safehouse. Once I know its location, I will give you further instruction.
Huang: Thanks. And may I say, I love the patronizing old turd act you've got going on.
(Hsin leaves, Huang follows the gang member)
Quarry: Some guy was following me, but I think I lost him.
Contact: Maybe he was just cruising... That's understandable with you carrying that fucking umbrella.
(Huang plants a bug on the gang's Chavos)
Contact: Come on, let's get out of here. Fucking idiot.
(They leave, Huang follows them)
Mission Replay description
"After a change of leadership, the Midtown Gangsters moved their main base of operations.
Hsin needed to know whether they remained loyal to him, so he had me follow one of their Korean gangbangers to find this 'secret' hideout."
