53 Belgrave Square

53 Belgrave Square is Jack Harkness’s London address and the site of Blake’s direct encounter with him. The house’s imposing scale and closed, quiet façade make it seem like a private world set apart from the surrounding city; Blake’s arrival turns that silent exterior into the threshold of a difficult conversation about Harkness’s alleged theft of money from his partners.

Setting and Address

Blake knows the address through letters she had written to Jack Harkness and sent to Wortalleth West, from where they were forwarded to him in London. There had been few letters, and fewer lately, but enough for her to know where to find him. Unlike Keith Perkins and Don, Blake has both Harkness’s phone number and his address, and she decides she can ask him about the accusations herself.

The address stands in a vast square lined with monumental white buildings, their pillars, parapets, high windows and steep chimneys suggesting, in Blake’s estimation, that each could house ten families. The central garden is locked behind railings, while embassies and their flags mark out much of the square. Against those signs of official presence, number 53 has no flag and no brass plate: only a pillared porch, broad steps, a large wooden door, a polished handle and a dolphin knocker. Blake sees a house that is conspicuously grand but gives little away about the life within it.

Blake’s Arrival

The square is silent and empty as Blake walks around it. A policeman patrols outside the Turkish Embassy, looking bored; nothing appears to be happening. At number 53, Blake looks up at windows reflecting a cloud-barred sky and wonders what kind of life Harkness leads behind the glass, closed off from the world. The house’s scale and its stillness leave her looking and wondering rather than immediately acting.

The quiet is broken when a second-floor window slides up with a squeal. Harkness leans out and recognizes Blake, calling down to check that it is really her. She smiles up at him, nervous and uncertain about what to say, before confirming that it is. The encounter begins across a vertical divide: he is above her at the window, while she has come to his door with a question she has chosen to put directly to him.

The Confrontation

Harkness presents himself as open to questions, spreading his hands and continuing to smile. Blake takes a sip of wine before asking whether he really did what he is accused of—stealing all the money from his partners. His smile does not falter, and he does not appear annoyed or evasive. Instead, he answers, “You can’t steal what already belongs to you, Blake.”

Blake immediately tests that assertion against the legal proceedings by asking whether the argument is playing well with the court. The exchange makes the address more than a marker of Harkness’s wealth or privacy: it becomes the setting where Blake’s personal access to him allows her to question him without an intermediary. His answer offers a claim of entitlement, not a denial that he took the money, and Blake’s follow-up keeps the distinction between his justification and the court’s judgment in view.
