DOCTOR FLOYD?

What is it, Hal?

THERE IS A MESSAGE FOR YOU.

Okay, Hal.  Who is calling?

NO IDENTIFICATION.

Very well.  Please give me the message.

MESSAGE AS FOLLOWS.  IT IS DANGEROUS TO RE-
MAIN HERE.  YOU MUST LEAVE WITHIN FIFTEEN RE-
PEAT FIFTEEN DAYS.

That is absolutely impossible.  Our launch
window does not open until twenty-six days
from now.  We do not have sufficient pro-
pellant for an earlier departure.

I AM AWARE OF THESE FACTS.  NEVERTHELESS YOU
MUST LEAVE WITHIN FIFTEEN DAYS.

I cannot take this warning seriously unless I
know its origin.  Who recorded it?

THIS IS NOT A RECORDING.

Then who is speaking to me?

I WAS DAVID BOWMAN.

I cannot accept that identification without
some proof.

I UNDERSTAND.  IT IS IMPORTANT THAT YOU BE-
LIEVE ME.  LOOK BEHIND YOU.
