Heathrow Airport

Heathrow Airport serves both as a real point of departure and as a stage on which departure can be performed. At Terminal 5, Blake begins her first flight and parts from Don; later, Harkness exploits the airport’s cameras to suggest to the authorities that he has flown abroad. The contrast makes the airport a threshold between separation and evasion, and between actually leaving and merely appearing to do so.

Terminal 5: Blake and Don part

In the departures hall, Don and Blake prepare to go their separate ways after working together. Blake is about to fly for the first time in her life, surrounded by travelers for whom flying is ordinary. Don has just bought her a phone, its plastic packaging still in his hand. Blake has avoided being easily contactable as a way of staying off the grid; now, their continuing work requires them to stay in touch.

Their parting marks a change in the practical terms of their partnership, not its end. Blake recognizes that they are a team even as the idea remains unfamiliar to her, and neither knows what awaits at the destination of their respective journeys. Don also gives her a credit card, reassuring her that he has others and will not be short of money. At the airport, their alliance becomes something they must carry beyond the shared stretch of the investigation: a phone and a means of payment accompany Blake into an uncertain next stage.

Harkness’s staged departure

The airport appears again when Harkness describes how he tried to make the authorities believe he had left the country. He left his car in the long-stay car park and deliberately walked in front of CCTV cameras inside Terminal Five, hoping the recorded images would support the impression that he had departed by air. He had not actually left: since then, he says, he had relied on lifts.

His account turns the airport’s ordinary infrastructure into a tool of deception. The cameras can establish that Harkness entered the terminal, but they do not establish that he boarded a plane. The supposed departure depends on what the authorities might infer from a trace that records presence without confirming the journey. When he sees Don’s MGB, he recognizes the car and pats its roof, presenting his improvised travel as a return to his student days; he says Fran had mentioned what car Don drove.

A threshold used in opposite ways

For Blake, Heathrow marks an actual departure into unfamiliar territory, while the phone and credit card Don gives her help preserve their connection across the separation. For Harkness, the same airport is useful precisely because its visible signs of departure can be mistaken for departure itself. One scene makes separation a practical and emotional transition; the other makes it a performance intended to mislead.

The two uses give the airport a role beyond backdrop. Its departures hall gathers travelers moving onward, but Harkness’s staged passage shows how the appearance of movement can be manufactured from a car left in long-stay parking and a walk before the cameras. Heathrow thus links the investigation’s personal partings with the tactics of concealment that continue to shape it.
