"Case?"Sherlock glared at him from the door, one hand on the doorknob. "Don't make me repeat myself. We're leaving in three minutes." He picked up a pair of trousers from the floor and threw them at John's head. "Are you listening to me, John? Shall I fetch you a jumper as well or do you think you can manage?"Sherlock's latest case might just be interfering with an important day of the year.
This is a fast-paced casefic that does an excellent job showing why John is the perfect friend for Sherlock Holmes, as happily devoted to their wild life as a man could be.
