"That's good little Vixen, just relax and keep the flow going," the Doctor spoke calmly as he felt the rush of the message shoot up the length of his arm and swirl through his head. Its sounds echoed through his mind with all the subtly of a rampaging bull. Although he could not make sense of it, he could hear the melody of the code soar through his head.
To him, the sound resembled the sound of crashing waves, the howl of the wind and the crackling of fire, all mixed with the delicate sound of the universe that sang in the background. Infinite and brilliant its in complexity and beauty.
"You know, something has been bothering me too," Sky spoke from her position in front of the computer screens. She was gazing up at them, watching the image of Strax standing guard in front of the TARDIS with curiosity whilst stroking the top of K-9's metal head. "How did the Cybermen get into our base?"
"What do you mean?" Gwen asked, getting to her feet and stretching before walking over to Sky's side.
"What I mean is, how did the Cybermen get past our jammer?" Sky said before reaching up and touching one of the screens, turning the channel over to a picture of Big Ben. "I'm not one hundred percent sure, but I don't remember deactivating the jammer in K-9 when we reached the base. We should have been invisible to them the entire time they launched their attack."
"So what are you suggesting? Can the Cybermen pick up our signal now?" Gwen asked, clutching her gun tightly as she looked over at the empty doorway warily.
"No, I'm saying they would need to lock on to something in order to find us," Sky said with a frown. "And I can't for the life of me figure out what it is."
"No!!!" Madame Vastra suddenly yelled from across the room, interrupting the discussion. Her sword clattered on the ground as she stepped back and fell into her seat as her legs gave out from under her. A look of pure despair clung to her green scaly face, her eyes were wide with shock. "I figured it out...I know what is wrong."
"You have?" Jenny asked with concern, sliding down next to Vastra. "What is it! Whats going on?"
"Oh my beloved I'm so sorry..." Madame Vastra whispered, grabbing Jenny's wrists and clutching them between her green scaly hands.
The message decoded and at that moment the Doctor, Robin and Harry were all treated to the sound of several violins playing in perfect sync, along with the grand melody of a chorus of trumpets, cellos, organs and more. The music spread out over the TARDIS and washed over the three of them, filling their heads with its majestic music.
The Doctor looked puzzled at the console and stepped forward to flick a few switches, as if hoping that doing so would shed some light on what they were supposed to be hearing. He ran his hand across the controls for a moment before turning back to Robin and frowning deeply.
"Okay...I have no idea what's going on," the Doctor said before letting out a little laugh. "I mean...I know this music, but why someone has decided to send it through the Eternal Code is beyond me."
The Doctor turned on his feet and pressed his ear to the console, stroking his finger around the buttons as he listened intently to the music that flooded from the heart of the ship.
"This music belongs to the London Symphony Orchestra. I would recognise their performance anywhere, I was part of them for a while. I played the triangle!" The Doctor exclaimed happily as he listened to the music. "There, you hear it? The sound of the violins, the cellos, the strings and the brass. Its wonderful!"
The Doctor stood up and frowned at the console before scratching his roughly shaven chin. "But, its still wrong. What is wrong with this picture? Why did our enemy send this music to the TARDIS? What's so special about it?" The Doctor asked before shrugging. "Well, I guess if you nit picked, the only thing that's wrong with it is that it's missing the percussion-"
The Doctor froze. His body became stone. He stared at the heart of the TARDIS with a look that would have seemed more befitting of someone hanging before a chasm. His eyes were wide and his skin had paled, his hands hand begun to shake as every single piece of the puzzle finally aligned to reveal the awful truth.
Beware the child of time
"It was you..." the Doctor spoke before turning towards Robin. "It was always you," he said softly before his eyes drifted over her shoulder
...and landed on Harry.
"You're right Doctor," Harry spoke as he looked into the Doctor's horrified gaze. A smile passing over his innocent lips as he stared at the Doctor with his big dark eyes.
"There is something missing from the music," Harry went on before stepping to one side of Robin and gazing up at the Doctor, his smile widening into a pleasant angelic grin.
The Doctor moved. Harry moved first.
The Doctor's hand was half way up to his coat pocket before Harry pressed down on the camera button. The flash lit up the area and blinded the Doctor, sending him stumbling back. Before the Doctor could regain his balance, Harry pulled out a golden device, no bigger than a cigar, and pointed it at the Doctor before snarling at him with all the ferocity of a demon.
A strip of gold light shot from the device and sliced through the Doctor's chest, sending him sprawling back against the console with a thud before he collapsed in a heap on the ground.
"Well..." Harry began as he pocketed the device. The ferocity vanishing from his face as he looked over the Doctor's body with a pleasant smile on his face. "That was satisfying."
