A stunned silence fell over the room, broken only by a harsh laugh from Sally.
"That's too bloody simple." She said.
"That's the beauty of it." John countered quickly. "If there are any of Mycroft's associates still bothered about us they'll expect us to come up with a clever, complicated plan."
"Is that likely?" Sherlock asked.
John shrugged and stood up.
"Look, we can discuss this 'til the cows come home but it won't change our position, and it won't change our plans."
"So, we pack up?"
"Yeah." Looking down at Sherlock John smiled. "If you can pack up the lab equipment, but we'll take your notes and stuff with us. I'll check up here to see if anything needs storing, and pack our clothes into two backpacks."
The younger man disappeared down the stairs.
"What about us?" Greg indicated himself and Sally.
John grabbed a pen and notepaper and drew two quick maps. He handed one to Greg.
"Head out this way, when you get here…." He indicated a road parallel to Baker Street, "you wait. Sally, you'll go this way about fifteen minutes later and meet up with him here."
"And come back here together."
"Right. Mrs H, can you go first?"
"Right you are dear," she nodded. "And I'll make a meal for when we all get back."
