The Annotated Autopsy of Agent A (short story)

The Annotated Autopsy of Agent A was the first story in The Book of the Enemy. It was written by the anthology editor Simon Bucher-Jones.

Summary
The Enemy are life-spores which infect history and transfigure it so that they were always there. Spores infect the human crew of the spaceship Narcissus and spread backwards along their lineage to the planet Earth. Thus the Enemy begins to attempt to bud in the mid-20th century, at first failing to get enough psychic energy to assert their new history. The Enemy comes close to success by infecting President John F. Kennedy in 1967 during his second term in office, but by chance the President dies of a heart attack just before he can be transformed.

An agent of the Great Houses comes to the morgue to examine Kennedy's body. Seeing that the Enemy will still be able to fester in Kennedy's timeline, the agent decides that Kennedy must be terminated at a point before he was infected with Enemy spores.
