you can't go up against assassination

The Eclipsed Celebrity Death Club:

The championship trophy for badly timed death, though, goes to a pair of British writers. Aldous Huxley, the author of Brave New World, died the same day as C.S. Lewis, who wrote the Chronicles of Narnia series. Unfortunately for both of their legacies, that day was November 22, 1963, just as John Kennedy's motorcade passed the Texas School Book Depository. Huxley, at least, made it interesting: At his request, his wife shot him up with LSD a couple of hours before the end, and he tripped his way out of this world. Which, if you're going to go to your reward without anyone's noticing, is probably not a bad way to end it all.
