House On Hollow Hill (The Housetrap Chronicles Book 3)

Sounds like a simple assignment. Randy and Bertha go undercover for a high class weekend in the country, all expenses paid. All they have to do is pretend to be somebody else while keeping a close eye on their host, Archibald Anthony, the famous Serial Painter, and mingle with the other guests, exchanging pleasantries. Their job? To keep Anthony alive until the long weekend is over and sort through the suspects when the bodies start falling.

Of course the guests include some of the top rungs of the social ladder: vampires, elves, hobgoblins, goblins, trolls, gremlins, plus the addition of the varied staff members loose on the estate. Strangely enough, almost everyone seems to have their own private agenda.
