message, which thus became one of the first to move on the direct wire
as a real, nontest item. S.I.S. received it a little after midnight. But PA-K2
was a low-priority system, and the message had originated in a consular
office. It was set aside to be worked on later.
Besides, S.I.S. had more important things to worry about. Like OP-20-
O, it was going frantic in a search for the 14th part. Captain Robert E.
Schukraft, head of the intercept section, and Frank B. Rowlett, the
civilian cryptanalyst in charge of the Japanese diplomatic solutions,
checked and rechecked to see whether one of the stations had picked it
up and had somehow neglected to forward it. The message preambles
had said that it existed, but they could find no trace of it. Neither
suspected that the Japanese Foreign Office had deliberately held up
transmission of this final conclusive part for security's sake.
