Goldfinger’s remark describes a progression from chance to suspicion. A single unusual event can reasonably be treated as accidental, while a second similar event may still be coincidence. By the third occurrence, however, he argues that repetition itself becomes evidence of deliberate interference.

The line is therefore about inference under uncertainty. It does not prove that repeated events are connected, but it captures the practical need to revise an explanation when the same pattern continues. What initially appears random may deserve closer scrutiny once recurrence makes accident less convincing.

In the context of the novel, the phrase reflects Goldfinger’s growing suspicion that Bond is not merely appearing by chance. More broadly, it expresses a principle of threat assessment: repeated anomalies can justify moving from passive observation to active investigation, while still requiring judgement about whether the apparent pattern is genuinely meaningful.
