This is an idea that I have has for a while. But I'm not sure where to take it (I just write I never plan anything out). So review and tell me where you would like it to go? Thank you.

"Doctor? What's this blue book?" Clara asked picking up an old tattered book. The spine was coming off and the cover was very battered. This obviously was a book that was opened regularly. Her voice echoed through the centre room of the TARDIS. The doctor appeared from one of the corridors with an arm full of tangled wires and metal. He pulled out bits and pieces and mumbled to himself and put it back in the pile.
"Sorry what did you say?" The doctor coming up the stairs to the console through the pile of useless of junk in his hands.
"What's this book?"Clara repeated waving the book around trying to get the doctor to look at it, he finally looked up from his twisted pile of junk and with a big crash on the ground the metal became more mess that the TARDIS would have to move because he never cleaned up after himself he looked up in amazement.
"Where did you get that?" The doctor whispered angrily rushing towards Clara looking like he was trying to protect her. His eyes darted from one side of the room to the other. "She could be here." he held his hands up with his thumb dancing around his fingertips like he was thinking. Clara clasped the book, her nails digging into the cover.
"You still haven't answered my question." Clara whispered forcefully
"Believe me Clara. Somethings you don't want to know?" The doctor turned back towards Clara looking at her "we could be in big trouble."
"You always say that when you don't want to explain something." Clara pointed out. "what do you mean she could be here? Who could be here?"
"Never mind that! Where did you get that book?" The doctor repeated forcefully
"It was just here? Does it matter?" Clara was trying to get the answer out of him but he wouldn't budge. She slowly opened up the book it creaked like the TARDIS door that the doctor still hasn't oiled. The doctor reached out for the book slamming the cover shut and snatched it off her, he held the book close to his body like a child protecting his toy that a grown up has taken.
"Spoilers." The doctor whispered stroking the book like a cat.
"Come on. Give me a look what could be so bad that you won't let me see? What is that book anyway?" Clara remarked reaching out for the book in the doctors possession he simply put his finger to his mouth and glared at Clara. She glared and pouted at him.
"Have you ever read a book and thought that happened to me. No. Wait bad example." The doctor interrupted himself like he usually does half way through conversation. He stopped and thought about what he was going to say. "Have you ever written a diary Clara?" He began again.
"Hasn't any young girl at one point? I myself haven't been able to keep one but I did try? Why?" Clara stated
"Because that's what it is my diary. Well when I say my diary it's not my diary. It's a diary-"
"DOCTOR! It's ok. It's timey-wimey" Clara interrupted.
"Yeah thats what it is timey-wimey." The doctor said softly he smiled at her. Clara's attention was brought to the fact that the pile of twisted metal that the doctor was holding when he entered the room had in fact disappeared.
"Er? Doctor?" She whispered slowly "where did the junk you were holding go?"
"It's not junk. It's a pile of TARDIS pieces. I'm thinking about fixing my chameleon circuit." The doctor whispered back feeling very proud of himself.
"Um. yeah. it's a pile of junk? Where did it go?" Clara repeated
The doctor turned swiftly. He rushed over and kneeled down and pulled out his sonic screwdriver from his pant pocket a drone came from the little gadget, he moved it around a bit and flicked it so the prongs were open he held it up and twisted it around in his hand his brow furrowed and he hit the top if his sonic screwdriver then put it back in his pocket.
"You may not like the answer Clara?" The doctor stood up and walked back towards Clara
"What do you mean?" Clara replied slowly
"Well. ah? Do you?" He began to pace around. "We sort of. Maybe. Have to go through the TARDIS again?" He cringed waiting for a scolding from Clara.
"What do you mean again?" Clara slowly asked. her voice filled with concern
"It doesn't matter but. What does matter is. We need to start now because this ship is infinite. It could take years to find the pile-"
"You still haven't answered my question." Clara raised her voice slightly
"It's in an echo room." The doctor mumbled
"In a what room?"
"An echo room. Ok! We need to go and find it! I don't know how but that book is involved in some way and I need to find out what" he rushed over to Clara raising his voice "hold this" Clara held out her hands the doctor handed back the book "hold onto it and don't drop it what ever you do!" She nodded in agreement a light smile appeared on her face reassuring the doctor. He pulled out his sonic once again and pointed it at the book the murmur that normally occurred was broken and the light was flickering the doctor hit the screwdriver against his hand and breathed on it and pointed it at the book once again the screwdriver still didn't work.
"Doctor there's no point trying to get it to work. We may as well just start looking for that echo room now?" Clara pulled the doctor away from the book and dragged him down the stairs to the endless hallways that were a head.

Again please review and tell me your ideas :)
