Bonus points for channeling King Henry II vs Archbishop of Canterbury, Thomas Becket.
OK, without looking it up, best guess...
What year was Thomas Beckett killed?
How many knights did it take to kill him?
What was his title at the time of his death?
Where was he killed?
No, I didn't know either. Well, the 3rd yeah.
You claim to know all about religious history, this should be easy. Enjoy...
