Fowler arrives at Mr. Chou's residence and asks for Mr. Heng. He doesn't seem to be in.
After a short delay, a woman there ushers Fowler to a place a few blocks away where he finds him.
Mr. Heng had heard the news of the attack. He's staying away from Mr. Chou's for a while. Even though he had nothing to do with the attack, it's the job of the police to find a culprit.
Fowler informs Mr. Heng that Pyle is to blame.
Mr. Heng agrees.
Fowler asks if Pyle is with the O.S.S., a U.S. intelligence agency. Mr. Heng surmises that the initials are different.
