Now just what happened that dark night when T. E. Lawrence crashed his motorcycle on a country road and died?

Was he killed by the Secret Service or the British Army because his views on the Middle East were giving the prime minister gas?
Was he killed by a homosexual Royal lover?
Did Faisal have him assasinated because of his failure to convince the British government to take favorable action in the Middle East?
Were the two boys on their bicycles the cause as the investigation had it?

Or was he just drunk?
