Martin's Drift is identified in the novel as a border post used to bring a BMW motorcycle into Botswana without papers. Its significance in the account lies in the mechanics of that passage: a cover story and money secured entry, while an address carried by the driver left a detail that could be traced.

Border post and motorcycle transfer

A report states that the motorcycle was brought through Martin's Drift on a three-tonner. It had no papers; the explanation given was that it belonged to a South African who had suffered an accident somewhere in Northern Botswana. The exchange frames the crossing as an arranged movement of a vehicle, rather than a documented passage under its own power.

Payment and recorded address

When asked whether the motorcycle had been allowed through, Williams answered that money had changed hands. The account does not specify who paid or received it. It adds that the driver had an address with him and that the address was copied down. That small recorded detail contrasts with the unpapered vehicle and informal payment: the transfer depended on evading normal documentation, yet it also left a potential point of identification.
