The Cold Voice from Book 2

Since reading book 6, I have started seriously wondering to what
extent Rowling has seriously misled us in providing false resolutions
to the mysteries she provides us in her books. One in particular,
that I wonder about, is the mystery of the cold voice that Harry hears
in Book 2.

Everyone is supposed to assume that the mystery is solved, and that
what Harry heard was the voice of the Basilisk he killed at the end.
But is that correct? There are a few problems with this solution.

First: when we meet the Basilisk, it never speaks. Harry never hears
it utter that cold voice. Riddle speaks to it, but it never speaks
back. If this were really the solution, it would be so simple for JKR
to provide a clear confirmation at this point.

Second: When Harry meets the Basilisk, it has grown truly enormous.
It is as thick around as an oak tree trunk. This enormour size might
allow it to travel the main "pipe" (large enough for a man) that leads
from below the castle up to Moaning Myrtle's first-floor bathroom, but
it is hardly likely that it can fit into the lesser pipe passages that
branch off from the main pipe and run throughout the school. And yet,
when Harry first hears the cold voice, he is in Lockhart's second-
floor office, upstairs from Moaning Myrtle's bathroom. How did it get
there?

Third: When Harry first hears the cold voice, it is speaking to
someone; ("Come to me; let me rip you; let me tear you; let me kill
you") and yet Lockhart and Harry are the only people present. The
only explanation that comes to mind is that the snake-creature is
speaking to Harry, hissing its hatred at him. But the Basilisk, as
far as we know, has nothing personal against Harry; it attacks because
it is ordered to, and has never been ordered to attack Harry. Even if
the voice is hissing at someone other than Harry, we still have got
loose end and an unsolved mystery.
