Wondermark by David Malki for September 02, 2016
"Yours truly, blah blah blah, etc." Now read it back to me. "To whom it may concern: at noon tomorrow, my plague will begin to infect the entire city. Unless, of course..." New paragraph... "Unless ten billion dollars is deposited into the following Swiss bank account." I don't know, it's sort of cold. Maybe make it "warmest regards."
