Wen Shu is an assumed Taiwanese national encountered in passing by Michael Thorton during his first contact with supposed CIA operative Steven Heck in Taipei. Upon entering Heck's place of business, Lucky 13 Dry Cleaning, he is invited into the back room where Heck and Shu are. Wen is tied to a chair, and has taken a beating from Heck in what appears to be an interrogation. Heck is about to pour dry cleaning fluid down his throat when Wen manages to point to a candy bowl on a table nearby with his head. Michael Thorton then watches as Steven Heck turns to grab his keys, the objective of his entire interrogation.
The relationship between Wen Shu and Steven Heck is never completely explained, nor is the hostility Heck displays towards him. It is mentioned by Heck in passing that Shu had somehow offended him and/or caused himself to seem untrustworthy. The exact reason is undisclosed. One possibility is that Wen Shu and Heck had some kind of disagreement or misunderstanding in the past that coincided or resulted in negative consequences. Another possibility is that Wen Shu never actually did anything at all, and Steven Heck (who is notably unstable by general observation) simply perceived wrongdoing on Wen Shu's part.
If the player holds a high reputation with Steven Heck, the latter will frame Wen Shu as the assassin who killed/attempted to kill Taiwanese President Ronald Sung in the aftermath of Operation True Heirs. Wen Shu will then be executed by the government as the assassin (regardless of whether Sung survived the assassination) of the nation's president.

- — The only things Michael Thorton hears Wen Shu say.
- "I appreciate that, Mike. You've always been a stand-up guy, y'know that? Not like Wen. No sir, not like Wen at all."
- — Steven Heck revealing his level of trusts.
- A copy of "The Catcher in the Rye" is found in Wen's residence when he is arrested. The book is notorious in conspiracy contexts as apparently being a choice read for several historical killers, including Lee Harvey Oswald, who assassinated President John F. Kennedy. It's likely that Heck planted the novel in his apartment, considering his obsession with conspiracy theories.
- Steven Heck can mention how "Good ol' Wen" always gets into "antics." This implies Wen has done things Heck has taken offense to numerous times. What these things are exactly is never specified.
