Brac Pack Halloween Murder Mystery — Lynn Hagen

Maverick, Christian, Zeus, and Panahasi decide to bring all four families together to throw the biggest Halloween bash of the century. There are costumes, ghoulish music, candied apples...and murder? When Gabby stumbles across a body in the foyer, the heat is on. It's up to Johnny, Keata, Gabby, and Nero to find out who committed murder, in what room, and with what weapon...and none of them have a clue--literally. But some are determined to keep the Scooby Doo team quiet. When Keata disappears, the investigative team must quickly find the culprit before he or she strikes again. Ah, but the added mystery is why Remus keeps losing his newly found mate.

Warning: Book contains bad investigative skills, outrageous costumes, off-the-wall dialogue, and moments that make anyone question who put the four mates in charge of the investigation in the first place.
