When they entered St. Barts hospital, Molly Hooper was already waiting for them. Lestrade called her and asked her to come. He said Sherlock's involved, so she came. Three men entered the room – a DI, a detective and a doctor. She smiled shyly. The doctor smiled faintly back, but the detective remained serious. She uncovered the dead body, revealing a tanned woman with a single wound on her forehead, caused by a gun. "The cause of death is pretty transparent." "Don't jump to conclusions too quickly, John. A gunshot is a possibility, but not necessarily the truth." "I've checked her blood for toxins, alcohol and drugs and found nothing. The gunshot is the cause of death." the woman said. The doctor chuckled, glad he was right this time. The detective looked at him seriously, and the smile vanished from his face. "What made you think it was Mycroft?" the detective asked the DI. "His hair was found on the body, it was his gun that fired the shot, and we found gunpowder on his clothes." "That is very persuading." John muttered. "Not at all. Someone could have easily taken some of my brother's clothes and steal his gun, use them to kill her, plant evidences on her and escape." "Oh, don't be ridiculous. You're bribed because he's your brother." "What was his motive?" The DI hesitated, surprised by the question. "Excuse me?" "What was his motive? You seem so certain that it was my brother who did this. If you're so convinced it was him, tell me what his motive was." "We don't know yet," Lestrade started. "Just like I thought. So you basically have no –" the detective interrupted. "But he's going to tell us." He continued. Both men were baffled. What is he talking about? "What do you mean, 'he's going to tell us'?" the doctor asked. "We have a reason to believe he's a murderer, so he can't walk away freely. And we know interrogating regularly won't work – he can beat any lie detector. So we're going to isolate him and create the perfect circumstances that'll make him tell us everything he knows." The way Lestrade spoke was strange to Sherlock. His expression was different, darker than usual, and there was something odd about his tone. He sounded almost… cruel. Sherlock's expression changed into a comprehending one. "You're going to torture him." "That's not what I said." "But it's what you meant." Greg kept his mouth shut, not saying a word. "Why?" Sherlock moved closer to the DI. "Why are behaving this way? Whoever's blackmailing you must've given you an excuse. I won't force you to tell me who is it, but I will make you tell me the excuse he provided you." "Why?" he asked quietly. "Because as soon as I prove the excuse wrong, my brother will be a free man." Lestrade took in a deep breath. "We assume that Ms. Jenkins discovered something your brother wanted to keep as a secret. He killed her to keep her quiet." "And what is that secret?" He hesitated. "Well?" Sherlock urged him. "Mycroft Holmes helped James Moriarty break into Pentonville Prison and the Bank of England and steal the Crown Jewels." "What?! That's insane!" John exclaimed. "It's the truth." Greg answered. "Sherlock, tell him that's crazy." The detective was paralyzed. "Sherlock?" What John didn't notice was that his friend was no longer there – he was deep inside his mind palace.
