A VERY well written adventure. Don't let the synopsis fool you, this scenario is more than you might imagine.
For starters, it's well executed. It starts out with a well organized investigative scenario which anticipates the many ways players can go, and doesn't railroad them. It's possible for the PCs to wrap things up quickly, efficiently and completely ignorant of the true horror that's ongoing.
And it is absolutely a horror scenario. Children have been abducted from their homes, never to be seen again. The secret notes describing how things were set in motion are chilling in their cruelty, and should the players actually find out what happened to the missing children? That's a whole deranged playground filled with terrifying encounters.
But, it's also an adventure, and that means the PCs have a chance to triumph. Not just to beat the bad guy or live to fight another day, but get the serious, big damn hero ending with a happily ever after for dozens of tortured souls.
Probably not, but the pathway is there and I admire the author for giving us that light despite all the darkness in this scenario. Also any GM who can't have a blast with Mrs. Hearting just isn't trying.
One quibble. I wasn't clear on how the so-called zombies wound up in their present state. Perhaps I missed it, but while I could fill in the gaps I wasn't sure how they wound up where they were or what caused their condition. Otherwise a fantastic adventure. I'd also advise including the red herring in the briefing documents, just to watch the players faces when they realize what story they are really in.
