the note

when you arrive at the heroine den, you see police cars

        and a man with grey hair and a tired face, much like John's. This man is tired in a different way; he is not tired from fatherhood and a painful past, but he is tiring from age. You watch him wave you over, and notice the police badge on his belt. As John and Mycroft walk ahead of you, towards the man, you notice their attires; Mycroft is wearing a gymsuit, while John wears a knitted sweater and jeans. As they greet the man with grey hair, you notice him and Mycroft keep eye contact for a second too long, and when they shake each other's hands, you see Mycroft intake a sharp breath. 

        "Greg," Mycroft says as you approach, "this is the unlucky passerby who happens to have become trapped in the wrath of my brother." Greg--the man with the grey hair--laughs, and looks at you, but returns his gaze to Mycroft.

        "Sherlock?" Greg asks the group. "He isn't here, is he? And what wrath?" John and Mycroft look to each other, and then to you. 

        "You don't know?" John asks Greg. "Sherlock has been leaving these notes around town for us to collect, and he sent the three of us here. Or four? What are you doing here?" 

        "Sherlock called me," Greg responds, "saying to go to this address in forty minutes, and that you must wait for John before leading a party inside. When we arrived I thought he was talking about a drug bust; about twenty men and women ran outside, all clearly high." 

        "Wait, Sherlock called you?" John exclaims. Mycroft seems fazed as well, his foot tapping on the dirt covered ground and his eyes staring in the distance. His skinny body is hunched on itself. 

        "Shit," Greg responds. 

        "Did he sound weird?" John says. 

        "He sounded rushed." 

        "Fuck." 

        Mycroft begins to cross the yellow police tape, and seeing what he is doing, John and Greg follow, at a running pace. You follow as well, confused, and for some reason, tired. 

        When you get inside the den you split up and search, and it is Greg who finds the next note, addressed to "Lestrade". When Greg opens the letter, he finds but one word. 

        Greg. 

        -S.H.

        A few seconds later, John gets a text from "Mary" to get Mycroft to meet her at Hyde Park. There is something for him.
