Grosvenor Square is the Mayfair rendezvous where Don Challenor and Gareth Lawler coordinate access to files from Ingrid Denner’s laptop. The open, ordinary setting—marked by the Roosevelt Memorial and crossed by hurried office workers—becomes useful cover for an operation whose success depends on inconspicuous timing and signals.

Setting and landmarks

Don and Blake use an A–Z map to establish the square’s proximity to the cafés on North Audley Street: Blake judges that Grosvenor Square is no more than five minutes away. The plan places Gareth at the Roosevelt Memorial while Don approaches Le Truc Vert from the opposite side of the street. The memorial and the square’s benches turn a broad public space into a practical meeting point, with the café close enough for Don to move between the two without drawing attention.

The rendezvous

Gareth waits on a bench near the Roosevelt Memorial, with his laptop open and his iPhone in hand. Dressed in trainers, jeans, a hoodie, and a white Nike cap pulled low, he blends among the office workers crossing the square. Don, watching from about twenty yards away, reads his anonymity as part of the disguise: Gareth can appear to dissolve into the crowd. Their greeting is no more than a faint nod before Gareth returns his attention to his phone and Don continues toward the café.

Don’s own appearance is designed to complete the deception. He wears a worn suit and frayed shirt, with uncombed hair and an unshaven chin; a plastic bottle labeled as sparkling water contains Bell’s whisky. Before reaching Le Truc Vert, he takes a drink and rolls it around his mouth so that the smell will support the impression of a middle-aged man who has dropped out of the race. After the meeting, he eats a peppermint before crossing back toward Gareth, unwilling to let the police mistake him for someone who has been drinking Scotch at breakfast.

Operational role

The square anchors a plan built around a short window and an unobtrusive signal. Blake intends to spend fifteen minutes with Ingrid and use a Sapper magnetic device if access to the laptop requires it. Don is to pass Gareth on the far side of the road; whether Blake’s teacup is in her hand or resting in its saucer will tell Don whether Gareth’s help is needed. The arrangement links the café encounter to the square without requiring an overt exchange.

When Don returns, he finds Gareth still bent over his laptop, shading the screen with one hand as he types with the other. Gareth has already accessed one of Ingrid’s files and is downloading the one labeled Jane Glasson question mark. The square is therefore more than a convenient landmark: its public anonymity lets the operation move from covert access to the transfer of information, while the apparently casual positions of its two men conceal their coordinated purpose.
