Horror Collector, Vol. 4 - Midori Sato - Bog

I got a chain letter. If I don't forward it to 99 people by midnight tonight, a ghost will haunt me, and I'll die--that sort of thing. I've never been the type to believe that kind of urban legend. But...recently I noticed a creepy woman staring at me all the time. No one else seems to see her! What's going on!? No way... Could the curse of the chain letter be real?
