The red dot on Moriarty's forehead, right between his eyes, meant only one thing. One false move and he was dead. And it also meant that somewhere Mycroft Holmes was lurking in the shadows. Moriarty wiped the tears from his eyes. He was frightened. Something quite unusual for him, mainly because he knew that Mycroft Holmes was a complete bastard with no heart whatsoever. He doubted if Mycroft would understand about Donald.
And of course with several guns pointing at him James Moriarty's inner seven year old was about to wet himself. He instinctively squirmed and tried to cross his legs and someone took that to be a provocation and pulled the trigger.
Mycroft Holmes, looking rather dashing in his black combat trousers and tactical vest, and Sherlock, managing to look even more dashing in his overcoat and a selection of dust and cobwebs. They arrived just in time to see James Moriarty squirming under the laser sites and hear a high powered rifle go off. And the large bony head of Donald the Diplodocus slide off of its neck and take the bullet. It did hit Moriarty on the head and he collapsed in a heap on the floor.
Mycroft was horrified. The bullet may have damaged the Cipher. And there was that bit about pointy sticks and all eternity he had really been hoping to avoid. Sherlock was horrified that they had missed Moriarty. And Moriarty was hugging Donald's head groggily.
"You saved me. Donald. You saved me. Are you all right?" Donald's rather thick skull seemed to be intact but there was an ugly hole right between his eyes. Donald seemed just a little put out about it.
"James Moriarty I am arresting you under the security of the realm act 1870. You have absolutely no rights whatsoever. Take him to The Tower." Mycroft was quite sexy when he was doing his servant of Her Majesty act. Sherlock saw David McDonald swoon a little out of the corner of his eye. That was handy to know.
"But is Donald okay?" For a man who had just been arrested for treason Moriarty seemed very unconcerned for himself. Sherlock might have been touched but for the fact that John was in hospital, in agony because of Moriarty and his bloody dinosaur.
"The Dinosaur's fine. You on the other hand..." And he kicked him squarely in the balls.
"That's enough Sherlock." But Mycroft looked like he quite wanted to join in.
