Prologue: Two years ago

Sherlock stood outside a building looking over it. Usually a thief never catches his interest. Boring, predictable, easy to find when you find the stolen goods. But this one's been tricky, swooping in and out with out a trace. Taking anything that catches it's eye from the shiniest to the dullest piece.

The cops called him somewhat of a mastermind. The people called him a bastard. The media just started comparing him to a Magpie.

Sherlock thought the name suited the thief. John was talking to an officer and left Sherlock with his phone. Bad service with his own phone. He felt John's phone vibrate and he sighed angrily still working out the crime scene.

Mary's number came on the screen. Sherlock groaned in annoyance and picked up.

"What is it?"

"Sherlock?"

Sherlock stopped before he could get into a rant when he realized Mary's voice filled with fear. He could hear cars zooming past.

"Mary? What's the matter," with those four words John was already jogging towards him.

"It's Rosie. She contracted a fever this morning, and it seems I can't get it too go down and it's dangerously rising too fast. I'm heading to the hospital," Mary said.

"What's going on," John asked and Sherlock ignored him for a second.

"Which hospital," at this John panicked.

Sherlock nodded to Mary's answer and thickly swallowed. They needed to get there as soon as possible.

"Rosie has a fever," Sherlock spoke before John could ask, "We need to get to the hospital now."

It took them at least a half an hour to get there. The reason for the traffic and calling Mrs. Hudson, Lestrade, and Molly.

When they finally got there Mary was in tears and was being comforted by Molly and Hudson. Lestrade was at the nurses counter talking to one. He nodded and then walked over to John and Sherlock.

"There's nothing on her condition yet. All we know her temperature is about 101.3 and is rising," Lestrade said rubbing his eyes.

John took a shaky breath and then walked towards his wife while Sherlock and Lestrade sit down next to Molly and Mrs. Hudson once Molly moved for John to take her place.

Five hours later they were still at the hospital and Sherlock was getting antsy. Finally a doctor walked in. A sigh escaped his lips but his frown deepened. There was a sad look in the doctors eyes.

"The Watson family," the doctor asked. All of them stood up silently and he sighed.

"The fever was bacterial. Sadly we weren't able to bring the fever down in time. I'm sorry," he said and Mary and John balled. The rest cried with them not knowing what the future held.
