Just as Doctor Who is known as "THE" Doctor although many other doctors exist, so in the White and Red Chess Kingdoms, though there are many knights in the service of their Queens, for each color there is "THE" Knight of that color.
In the chessboard-patterned palace of the White Chess Kingdom, "THE" White Knight, the one who looks like Lloyd Bridges, is summoned to receive instructions from the White Queen.
"Sir Knight, you were in the Hearts Kingdom with us on our croquet visit recently; but unlike your King and myself, you mingled with the castle staff of the Hearts castle. Did you at that time receive any impression of something amiss?"
"No, Your Majesty, unless it was amiss for some persons from outside of Wonderland to be visiting there also at the time. When I saw Alice, with whom we are acquainted, she certainly gave no sign of worrying about anything. May I ask what is troubling Your Majesty?"
"Weather," said the White Chess Queen. "Have you not noticed that it has been unseasonably cold these last two or three days? The heavy clouds appear to have blown our way from the general direction of the Hearts and Clubs card kingdoms, indeed coming barely after we and the Red Kingdom party returned home from the croquet visit."
"Am I to understand that Your Majesty wishes me to investigate this matter?"
"Even so, Sir Knight. Take with you two or three other knights, some pawns, and the White-Squares Bishop. Do not assume that there are enemies afoot, but do be on your guard. Learn what you can about whatever has been happening in the Card Kingdoms."
"I hear and obey, Your Majesty."
