Twenty years ago, Nathan Munn rented an apartment in Montreal with a couple of friends. What happened next lands somewhere between The Money Pit and The Amityville Horror. A perfect spooky-season read.

I woke up, drenched in sweat, to find a steady rain pelting the window. I was so disturbed I didn’t sleep again that night. For the next few weeks, I kept the light on and my door open after dark. I was 23 years old.

That was just the beginning.
