Prince Alfred was the only heir, and from the day he was born, he was never a well child.
The King wanted another son, because it was obvious that Alfred would never rule. So, he hired assassins to kidnap and kill the queen so he could marry again.
Alfred knew that his father had his mother killed, so he had to kill his father’s mistresses.
He poisoned the first four before his father had the cook replaced.
When Alfred stabbed the fifth mistress himself, The King smiled.
“I believe you’re well enough to rule,” he said.
Then Albert stabbed him.
