"You shall depart freely. Caution enjoins me to have you arrested and garroted within this hour. Either you are a charlatan and deserve it or a mortal danger and require it. However, I deem you a sensible man who will withdraw to his obscurity. And I am grateful to you for a fascinating glimpse of—what is best left alone."
January 1, 1970
