Nono, it's not KSMs.
But i'm more interested of why you did such a strong response
concurring with JTB. 
We'll look thru the findings and discuss objectively yea?
Personally, i find the commentary below doesnt fully satisfy
me.
But it does give some perspective to look at and consider what
happen again.
Then again, even if people were to subscribe to this point of view
in 1 Sam 28. There are also other questions rushing in.

Of 1 Samuel 28:11-20 as well as the whole chapter.
Matthew Henry's Commentary
If Saul had thought it necessary to his conversation with Samuel
that the body of Samuel should be called out of the grave, he would
have taken the witch with him to Ramah, where his sepulchre was;
but the design was wholly upon his soul, which yet, if it became
visible, was expected to appear in the usual resemblance of the
body; and God permitted the devil, to answer the design, to put on
Samuel's shape, that those who would not receive the love of the
truth might be given up to strong delusions and believe a lie. That
it could not be the soul of Samuel himself they might easily
apprehend when it ascended out of the earth,
'for the spirit of a man, much
more of a good man, goes upward' Eccl. 3:21. But, if people
will be deceived, it is just with God to say, "Let them be
deceived; That the devil, by the divine
permission, should be able to personate Samuel is not strange,
since he can transform himself into an angel of light! nor is it
strange that he should be permitted to do it upon this
occasion, that Saul might be driven to despair, by enquiring
of the devil, since he would not, in a right manner, enquire of the
Lord, by which he might have had comfort.
his heart being wretchedly hardened by the deceitfulness of sin.
Saul, it seems, was not permitted to see any manner of similitude
himself, but he must take the woman's word for it, that she saw an
old man covered with a mantle, or robe, the habit of a judge, which
Samuel had sometimes worn, and some think it was for the sake of
that, and the majesty of its aspect,
We have here the conference between Saul and Satan. Saul came in
disguise (v. 
, but Satan soon discovered him, v. 12.
Satan comes in disguise, in the disguise of Samuel's mantle, and
Saul cannot discover him. Such is the disadvantage we labour under,
in wrestling with the rulers of the darkness of this world, that
they know us, while we are ignorant of their wiles and
devices.
Why hast thou disquieted me to bring me up? To us this discovers
that it was an evil spirit that personated Samuel;
for it is not in the power of witches to
disturb the rest of good men and to bring them back into the world
when they please; nor would the true Samuel have acknowledged such
a power in magical arts: but to Saul this was a proper
device of Satan's, to draw veneration from him, to possess him with
an opinion of the power of divination, and so to rivet him in the
devil's interests.
Nothing is said to reconcile him to
David, but all tends rather to exasperate him against David and
widen the breach. Yet, to make him believe that he was Samuel, the
apparition affirmed that it was God who spoke by him. The devil
knows how to speak with an air of religion, and can teach false
apostles to transform themselves into the apostles of Christ and
imitate their language. Those who use spells and charms, and plead,
in defence of them, that they find nothing in them but what is
good, may remember what good words the devil here spoke, and yet
with what a malicious design.
He upbraids him with his disobedience to the command of God in not
destroying the Amalekites, v. 18.
Satan had helped him to palliate and excuse that sin when Samuel
was dealing with him to bring him to repentance, but now he
aggravates it, to make him despair of God's mercy. See what those
get that hearken to Satan's temptations. He himself will be their
accuser, and insult over them.
And see whom those resemble that allure others to that which is
evil and reproach them for it when they have done. He foretels his
approaching ruin, v. 19. That his army should be routed by the
Philistines.
This is twice mentioned: The Lord shall deliver Israel into the
hand of the Philistines. This he might foresee, by considering the
superior strength and number of the Philistines, the weakness of
the armies of Israel, Saul's terror, and especially God's departure
from them.
Yet, to personate a prophet, he very gravely ascribes it once and
again to God: The Lord shall do it.
That he and his sons should be slain in the battle: Tomorrow, that
is, in a little time (and, supposing that it was now after
midnight, I see not but it may be taken strictly for the very next
day after that which had now begun), thou and thy sons shall be
with me, that is, in the state of the dead, separate from the
body.
Had this been the true Samuel, he could
not have foretold the event unless God had revealed it to him; and,
though it were an evil spirit, God might by him foretel it;
as we read of an evil spirit that foresaw Ahab's fall at
Ramoth-Gilead and was instrumental in it (1 Ki. 22:20, etc.),
as perhaps this evil spirit was, by the
divine permission, in Saul's destruction. That evil spirit
flattered Ahab, this frightened Saul, and both that they might
fall; so miserable are those that are under the power of Satan;
for, whether he rage or laugh, there is no rest, Prov. 29:9.
