The Prince Charles Dam in Central Africa had broken and thousands had drowned because those in charge had relegated a warning letter to the cylindrical file.

A mine cave-in in Canada had extinguished three lives because a similar letter had been ignored.

By the time the fifth letter had been received, the S.M.M.R. had received the information and had begun its investigation. As an ex officio organ of the United States Government, it had ways and means of getting hold of the originals of the letters which had been received by the responsible persons in each of the disasters. All had been sent by the same man; all had been typed on the same machine; all had been mailed in New York.

When the sixth warning had come to the offices of Caribbean Trans-Air, the S.M.M.R., working through the FBI, had persuaded the company's officials to take the regularly scheduled aircraft off the run and substitute another while the regular ship was carefully inspected.
