"So what's the -" John asked.
"Try a better question." Sherlock interrupted.
"Mycroft and Evensley are in trouble. What are we going to do about it?" John asked.
"Nothing. Mycroft has the best security protection in the world. He's the British Government." Sherlock sighed.
"Then what will we do?"
"Try to stay alive."
"What?"
"Ask a stupid question, get a stupid answer. C'mon John, think!" Sherlock said.
"Ummm...."
Sherlock turns to face you, "What do you think we should do?"

"Give a sacrifice or protect your sister is a priority..?" she wasn't sure

"Sacrifice? What do you mean?" Sherlock asked.

"Guess. Give him what he wants or people die."

"Sorry, but no. You aren't marrying that psychopath, and neither is Evensley. We're going to protect her, and you, at all costs." Sherlock dashed outside to hail a cab.

"Tell me when someone dies." she rolled her eyes and looked at John, deciding to follow him, "Still doesn't understand sarcasm then."

A few hours later, the trio pulled up to Mycroft's large estate. Sherlock stepped out of the cab and paid the driver.
John let out a gasp. "Mycroft lives here?"
"Yes." Sherlock said woodenly. He motioned for you and John to follow.

he followed John, "How much time until he gets a lead, then?"

"Probably a few minutes. When Evensley and Sherlock put their heads together, this case is just about solved." John said. Sherlock walked over to an ebony-haired woman who was pottering around the garden. She looked up and waved to Sherlock.
"Hello Sher! How's work?" she asked, waddling over to him.
Sherlock hugged her. "Confusing. How's the baby?"
"The doctor said he's due in about a month."
"We need some help with a case." Sherlock said blandly. "It concerns Moriarty."
"Oh! Do come inside then! Mycroft just got home a few moments before you." she said, heading towards the door. Sherlock motioned for you and John to follow...

She followed after John awkwardly.
