And it was used. The passageway served its purpose: it allowed John Darwin to move between the adjacent properties, to visit his wife, to maintain some version of domestic life, while being officially dead. For the years he lived next door—perhaps from February 2003 until some point before the family home was sold in October 2007, though the precise duration of his residence in number 4 is not established exactly—the passageway was a daily feature of their existence.
When the couple left for Panama, or when the properties were prepared for sale, the passageway was decommissioned. The breeze blocks set in cement, the blocked opening—these were attempts to erase the evidence of what had been there. They were not entirely successful. The new owner, John Duffield, found the opening. He showed it to police.
There is something about this object—this particular physical thing, this coffin-shaped doorway hidden behind a fake cupboard back in a bedroom with sickly green walls—that resists reduction to the abstract language of fraud law. It is the most concrete, most specific, most domestic artifact of what the Darwins built. All the insurance filings and pension claims and money transfers and passport applications were conducted on paper, through channels. The passageway was built with hands, in a house, where people lived.
It is the closest thing the Darwin case has to a monument.
