Given the cover identity of merchant seaman Harry McEvoy, he finds lodgings in the Falls Road area and secures a job in a scrapyard. He dates a Catholic, Josephine Laverty, and unknowingly encounters Downes in a local club, which is raided by the British Army. A British soldier recognises Harry but ignores him and arrests Downes, who is interrogated but set free. Harry tips off his superiors that the killer was at the club and that Theresa, a girl at whose family home Billy stayed the night while on the run, knows his name. Theresa is arrested, but caught between the police interrogator Rennie and her fear of the IRA if she talks, she hangs herself in prison before revealing Downes' identity. When Josephine realises that Harry must have passed on the information about Theresa, she tells him to leave while he can, but he refuses, saying Danby's killer cannot be allowed to get away with the murder.
