Reader,

You are in danger! Unimaginable danger. Run. Hide. Now!

I don’t believe in God or luck, yet here I pray to both: let someone survive to find this warning. If one survives, then others might and perhaps those few can keep it alive. It. Us. The human race.

Stop reading this until you’re safe. Get away from other people. Look no one in the eye. Let no one get close. They need to be close to take you over.

The first irony. The only hope of saving what’s left of the human race is to isolate every survivor.

Here’s another. I did what I did for the good of humanity.

My ambition was always to make a lasting contribution. I would dedicate my extraordinary intellect to do science so important that my name would live forever. My focus was the human mind, a stimulating challenge. Despite centuries of scrutiny, understanding of consciousness remains elusive.

I happened upon an obscure study. In it, the author detailed a modestly clever experiment to locate consciousness. What was remarkable was that one subject died during the experiment and the researcher tracked consciousness — after death.

An absurd claim, yet something in it spoke truth to me. I couldn’t believe it but I couldn’t let it go. Eventually, I tracked down the author, retired from a third-rate academic career. I still cannot confirm whether he was collaborator as well as victim.

I was not trained to respect instinct, so I dismissed the uneasiness that swept me when he answered his door. I now know that feeling well. It is the first sign that a gate is open nearby.

Within each of us is a gate to a beyond. I have not determined whether that place is our afterlife, but it is a wild treacherous place we cannot enter or survive. We can only live with our gates locked tight.

His gate was ajar.

Horrible things wait on the other side. They wait to cross over and take us. They are — evil. I have never used that word except to describe them.

Get too close to an open gate and your gate opens, too. Another thing comes over, another human is lost.

The author had long been a recluse, struggling to lock his gate again. His efforts to warn me away used too much energy and attention. They took him while I observed. His eyes went blank, swiveled, discovered me with a flash of hungry curiosity.

They’re slow when they first come through. I ran away that day.

I’ve studied them ever since. I’ve slept too little and learned so much. But not enough. Their spread has accelerated. Suddenly they’re everywhere.

Some of us seem to be immune to them. Perhaps we can hide, repopulate, come back against them.

If only I had sounded an earlier alarm. Perhaps someone would have believed. I thought I could solve this problem without destroying my work, my reputation. Instead, I kept their secret.

Forgive me.
