"Your Majesty, may I present my brother, Sherlock Holmes," Mycroft said, with a stiff, rather nervous bow.
Mycroft watched with relief as Sherlock also bowed, but his relief disappeared completely when, by way of conversation, Sherlock said, "I can deduce from the look of relief upon your face, the faint scent of that cheap lavender soap in common use in most public facilities, and the small piece of toilet tissue attached to your left shoe, that Your Majesty has recently been to the loo."
It came as no surprise to anyone that both Mycroft and Sherlock Holmes were quickly removed from the Queen's presence and ordered not never to return to the palace again.
