Lord of the Wings by Donna Andrews

It is Halloween time in the wacky Virgina town of Caerphilly and they are holding their first ever week long Halloween festival.  This time, though, Meg Langslow is not in charge. Mayor Randall Shiffley hired Lydia Van Meter to handle it only she's botching it big time and driving Meg nuts with asking her opinion and doing the opposite or making her come down to her office to talk about something she needs to deal with that Meg already knows about and was on her way to handling.  Meg is in charge of the Visitor's Relation Police Liason Patrol or better known as the Goblin Patrol.  They handle problems on the ground downtown, at the Haunted House and Fairgrounds, and at the Zoo.

Things begin to go wrong from the start when Dr. Smoot the former coroner who is the resident guy who dresses as a vampire year round. His house is an old Victorian and he has opened a Caerphilly museum in the basement. His house is where the Haunted House is located at. He calls saying people have broken into it the night before but have taken nothing as far as he can tell.  Then at the zoo, that day Meg's grandfather, the zoo's owner, finds a severed hand that proves to be fake and inside the dark alligator section a severed foot, also fake, is found by Meg and Michael's twin boys' first-grade class who are touring the zoo that day.

The culprit who put the foot there is caught and confesses something about an "adventure" and a
"quest" and has on him a list of five things to do which leaves them to believe that some sort of scavenger hunt is going on.  But the young man isn't saying much more only that he now won't be able to advance to the next level, so there are more pranks to be played and Sherrif Burke says he has reported some odd things going on in town.

These scavenger hunters are causing havoc and worse. A body is found shot in the woods and discovered to be a conman.  Is he the man behind the games, and if so who's running the games now? The Chief is welcoming Meg's help on this one since his office is spread thin due to the festival and none of it makes much sense.  Andrews delivers on another funny mystery that's a real treat.
