Mycroft Holmes did not appreciate being woken up a full three point five minutes prior to his usual seven o'clock alarm.

He tried to remember his appointments for the day. There was the PM at eleven. But he knew better than to call this early. MOD? MI-6?

He reached for his phone.

He couldn't read the display without putting in his contact lenses, but he could see letters, not numbers—a saved contact, then. If it was…

"MYCROFT!"

It was. He added "divert Sherlock's calls to John's number" to his mental diary.

"MYCROFT! TAKE CARE OF OUR MOUSE PROBLEM IMMEDIATELY!"
