Out of the corner of his eye Sherlock noticed something. He wasn't sure if it was a trick of the light or if the statue had actually moved. "John, did you see that?" John looked at Sherlock in confusion "See what?" Sherlock muttered something under his breath. It must have just been a trick of the light. Must've been, couldn't be anything else... right?

Sherlock went back to deducing the crime. He solved it within 10 minutes. As he was walking away he was sure that statue was closer. He walked up to it and began to examine it, followed by a very confused John. "Sherlock? What are you doing?"

"Don't you see? The statue's moved. When we got here it was over there," he said, pointing towards a gravestone about 5 metres back. "John, I don't think this is just any statue."

"Then what do you think it is?"

Sherlock smiled and said, "Something new!"

He went back the next day to find the statue had vanished entirely. He had to know what was going on. Statues don't just vanish into thin air... right? He pulled out his phone and hacked into the security cameras. He downloaded the footage from the last week hoping to find the answers he needed.

First day: Statue was at the gravestone Sherlock had seen it at with John

Second day: Same as first.

Third day: Same as first.

Fourth day: Same as first.

Fifth day: Same as first.

Sixth day: Same as first until Sherlock and John showed up. Moved 5 metres.

Seventh day: Gone!

Was this the work of Moriarty trying to trick him? Surely not? Why would Moriarty even do that? Better check just to be safe. Sherlock sent a quick text to Moriarty.

Are you trying to trick me? -SH

What are you talking about? -JM

The statue. It moved. -SH

Still don't know what you're talking about. -JM

So it wasn't you then? -SH

no. -JM

If this wasn't one of Moriarty's tricks then what was it? His phone flashed indicating a text.

Meet me at St Barts... NOW! -JM

On my way. -SH

Sherlock called a cab and told the driver to take him to St Barts. He went inside and asked Molly if she knew where Moriarty was. "Follow me." She led him towards a room with the number 3 on the door. Sherlock entered the room but was surprised at what he found. Lying in a bed in the room was an old man. "Sherlock!" Was this some sort of sick joke? What was Moriarty playing at?

Then he noticed the man's wallet. Inside it were the exact same things Moriarty had. Moriarty wouldn't just give this stuff away to play a joke, right? The man spoke in a croaky voice "Sherlock. It's me, Moriarty. You have to call the doctor. The statues... the statues are moving again."

"What do you mean... again?"

Moriarty was crying silent tears "1973."

"What?" There was no response. Sherlock knew Moriarty was dead. He silently left the room and trudged back to 221B Baker St. He walked inside slamming the door behind him. John came up to him and asked "Are you alright?"

He sighed and said "John, Moriarty's dead."

John's face flashed in horror. "Are you serious?"

"Do you think I'd make something like that up?"

John shook his head. "I suppose not." Sherlock pulled out his phone and began texting. John looked at him and asked "Who are you texting?"

"The Doctor."

Apparently we need your help. -SH

What is it this time? -The D

Come to 221B Baker St. I'll explain everything.-SH

See you soon. -The D

Before Sherlock could tell John what was about to happen, the TARDIS materialised.

The Doctor stepped out. "Hello again!" Sherlock smiled at him and said in a mocking tone "Nice to see you again 'DOCTOR'."

"What's the problem?"

Sherlock explained about the moving statues and Moriarty's dying words. The Doctor sighed disapprovingly. "I thought they were all dead."

John looked at him with a look of confusion on his face. "What is supposed to be dead?"

"The Weeping Angels." Noticing the confused look on John's face he explained further.

"The Weeping Angels are a race older than time itself, they take the form of an ordinary stone statue. They're hidden in plain sight. They can only move if they aren't being observed. If you so much as blink around one, they could send you back in time."

"So where's our Moriarty then?"

The Doctor looked over at Sherlock and asked "What was the year he said?" "1973" The Doctor ushered them over to the TARDIS. They stepped inside. Sherlock pulled out his phone and sent a text.

Be back late, can you make us some tea? -SH

Not your housekeeper -Mrs H

Sherlock put his phone in his pocket and walked off down the hallway calling behind "Text me when we land!" With that he was gone. The doctor pushed some buttons sending the TARDIS rattling through time and space to 1973. John had to shout over the sound the TARDIS was making to be heard. "IS IT ALWAYS LIKE THIS?"

"YES!"

Meanwhile at 221B Baker St.

"They've been gone a week now." Mrs Hudson stated. Lestrade sighed and pulled out his phone to text Sherlock.

Where are you? -GL

I've only been gone an hour? -SH

Sherlock! It's been a week! -GL

Has it? -SH

Yes. Have you been deleting stuff again? -GL

No. Can you stop texting me, I'm busy. -SH

Doing what!? -GL

An experiment -SH

SHERLOCK! -GL

His phone went silent. Mrs Hudson had tried to text John earlier in the week but had had no reply. She hadn't realised why until she found John's phone smashed and in the fridge. What on Earth Sherlock had done she didn't want to know.

Back in the TARDIS

After much difficulty the Doctor had finally managed to land the TARDIS in 1973.

We've landed -The D

Coming. -SH

P.S. you might want to avoid the lab for a bit. -SH

What did you do this time? -The D

Mutated some milk. -SH

How did you manage that? -The D

It was an experiment! -SH

Minutes later Sherlock appeared in the console room. "You actually managed to land here?"

The Doctor nodded and said "Well you managed to mutate milk."

"Fair point."
