ARCHIVIST’S ANNEX — undated.

You will have noticed the arithmetic. The seal runs to 2037. It is not 2037. Therefore this is not a declassification, and nobody authorised it. Call it what it is: the thirteenth reading, on the only frequency he could never seize.

Twelve numbers were read and silenced, each on its anniversary, heard by the sea, the duty log, and no one else. The thirteenth was never aired. He saw to that on the 9th of October 1987, and he retired in due course with a clock and a citation, and he is old now. His number is printed above, in his own signature block — plain, un-shifted, exactly as a ledger entry is never written — where it has waited thirty-nine years for a voice.

A number is read when it is heard.

You have just heard it.

File under: OPERATION 13. Groups: thirteen. Reading: complete. The lamp turns for the ships that cannot see the rocks.
