Barty sighed. "If it was as easy as that I would have done."
He wet his lips. It was probably easiest just to tell her the whole. The Aurors would have had their own slant on it.
"It was Bellatrix Lestrange who brought me back. I got the impression that the reporting of it was sketchy at the time, but I was given the Dementor's kiss after assisting in the Dark Lord's resurrection."
He paused, sorting through the distant memories of his triumph, and trying to settle his anger towards Bellatrix.
"My soul was dead, but Bellatrix recovered my living body and put somebody else's soul inside me. I wish I could argue that it was only the influence of my own soul that made me hurt others, but... but when I first woke up I followed Lestrange and killed Mud- Muggleborns.
"So both souls were tainted. It was only later that I ran away from Lestrange and tried to start over. I murdered as both Barty Crouch Jnr and 'Barty Elias ap Rilind Hedera' Gringotts had on their records. I can't plead innocence on any count. The two souls have fused together, and I feel detached from my memories of both lives, but I can't pretend that I am innocent."
