Please meet me in the Forbidden Forest at Midnight. You can come earlier but no earlier than 11:30. Don't worry. I've warded out all the creatures and things that could spook us with a spell. I have something important to tell you. 
Melody   
Note: Keep going until the heart of the forest but when you see me, stop    

"Leona, what's wrong?" I whispered. "It's half ten, why are you sitting up."  
"Read this."   
I read it, and I was shocked. "But Melody's so shy."   
"Perhaps she's in the edge of the forest and we're misunderstanding the instructions."  
"Melody?" I whispered looking at Melody's bed. "She's not here. I know it says 11:30 but she'll already be there."   
"Yeah, I'll go. Bye!"   
"Bye! Be safe!"    
"Actually, can you come?"  
"Sure."   
We had to walk very quietly until we reached the dark forest.     
"Hello? Melody?" Leona called.   
"There's movement over there!" I whisper-shouted and we ran towards it.   
"It's gone! Where's Melody?"  
"Are we going to do it?" Said a male voice.
"Do what?" Said a female voice
"What do you think? Kill her!"  
"No! Not yet. Leave her here. Then the other girl will come too."  
"We-are-going-to-". 
"No."  
The man sighed. "OK."  
"MELODY!" Leona screamed. "Look!"   
Melody was tied to a thick tree. She wasn't unconscious but she looked in pain.  
"There she is!" The male voice spoke. They still couldn't see them properly but they could see the edges of their bodies. They were hiding behind a tree.   
"Accio gi-"    
"Diffindo!" Leona shouted, pointing it at the ropes.  
It created a hole in the tree, but other than that, it sliced the ropes cleanly and the voices broke out again.  
"Run away!" The female voice commanded.    
"Cowardly!" The man shouted.    
"Please."   
"Fine."   
Then footsteps could be heard as they ran over to Melody. Her blonde hair was dirty and her clothes had little rips in them.   
"Thank you!" Exclaimed Melody. "That spell was amazing."   
"It's alright. Are you OK?" Leona asked.    
"Yes, I'm fine, thanks. Just a bit scared." 
"OK."   
"How did you find me anyway?"   
"Leona got a letter. I suspect it was those people trying to lead us here." I explained "Let's get back to bed."
