Horror-Ween(2019)

Keri Wolf hadn’t imagined she’d be called out as Halloween neared—she was still in the academy and Joe . . .

Well, Joe was just becoming accustomed to the idea that she had decided to join him as an agent, having the special talent that allowed an agent to become Krewe.
But that Halloween she was going to become Krewe—as a consultant. Because a killer who had struck three times before was threatening to kill again, this time at a Halloween theme park in Louisiana.

There were plenty of able agents with the Krewe, in Joe Dunhill’s mind. Why Keri and him, when he was comparatively new in his position and she wasn’t even out of the academy yet?

But there was a method to the madness. Because Keri had written one of her acclaimed non-fiction books on the killings that had first taken place in Massachusetts. She knew the woman who had called in a warning, supposedly given to her by a Revolutionary War soldier who had made his way from Massachusetts to Louisiana to tell her that it would happen again--just as the killer sent his rhyme for that year.

“Trick or treat, trick or treat
Not looking for anything good to eat
Must may be that I’m up for a trick
Think this time, a nice big pick.”
