It is then revealed that Elise is in fact an agent from scotland yard who may have become Pearce's ally. She fears for Franks safety so therefore agrees to a sting operation. Elise later attends a ball where she assumes the real Pearce will be. An envelope is placed on the table in front of her and the man hastily walks away, she assumes that this is Pearce and promptly walks after him. On her pursuit Frank intersects her and declares his love for her. He is then hauled away by the police, Elise opens the envelope from Pearce to find a note mentioning rendezvous point, she heads off in boat to rendezvous point, but is tailed by the gangsters and closely followed by the police, who have Frank tied up in there boat to stop him from obstructing the investigation.
