midnight
W. , a few hundred miles east by north of the fairy-like mountaintop of the Bermudas . Our charts showed the Lowlands there to run down to what once was measured as nearly three thousand fathoms -- called now eighteen thousand feet below the zero-height . A broken region , a depth-ridge fairly level , and no Lowland sea , nor any settlements in the neighborhood . The time was set at an hour before midnight . No mail , passenger or freight flyers were scheduled to pass near there at that hour , and , save for some chance private craft , we would be undisturbed . The ransom gold was available to Hanley . He had said he would bring it in his personal Wasp .
