Good Thinking, Batman - a 221B for JAL who challenged and dared...

It was a tense situation, the robbers were swinging their firearms around in an alarming manner.

"We need to create a distraction!"

"Good thinking, Batman!" Sherlock hissed through his teeth.

"I have you know that I've lost a lot of weight recently," the elder Holmes said with a pinched expression.

Sherlock rolled his eyes in disbelief.

"Ladies, ladies! Put down your handbags!" John hissed from across the room.

"Your idea of a diet is somewhat compromised by consuming three jammy dodgers with coffee earlier, with-" Sherlock leant towards Mycroft sniffing slightly, "-one, no two, spoons of sugar."

"Be quiet over there!" The sawn-off shotgun was waving menacingly towards them now.

"I refuse to be held hostage with this nincompoop!" Mycroft said loudly, rising to his feet. All eyes were on him as John threw himself bodily onto the first gunman. Sherlock sprang up knocking the gun out of the hand of their other assailant.

"You do know that I said Batman and not fat man, don't you?" Sherlock said with a smirk.

"And you do know, dear brother, that as distractions go, that was quite a doozy as cousin Harry would likely say."

"14th cousins twice removed hardly count as cousins, but I do get your drift." Sherlock smiled companionably at his brother. "And, thank you for being my batman."

NB: A batman (or batwoman) is a soldier or airman assigned to a commissioned officer as a personal servant. I fully expect that it'll be handbags at dawn after that last comment!
