MI-5 has recently opened its files and certain heretofore unknown facts have come to light.
It seems that Lord Kitchner, when he was in Egypt with his troops preparing to go to Khartoum to try to rescue General Gordon, contracted a skin condition that proved untreatable. Over the course of time, the itching caused by the condition affected his mind to the extent that his grip on reality began to slip.
By the time the campaign was over, he was as mad as a hatter and decided that the Monarchy must be overthrown and replaced with a military dictatorship with himself at the head. Since he was a hero to the British people, the whole matter was hushed up and he was kept in seclusion until a cure for the skin problem could be found.
A cure was found, administered, and the Generals sanity returned.
As I said, MI-5 has kept this secret until recently. So good was their security that no word of it ever got out except for the name given to the file wherein the details were kept and even that gave no real clue. Most people simply took it as a nonsense phrase used in regard to small children.
The name of the file was.....
The "Itchy Kitchy Coup"
