Counterfeit Magic

When Ava comes to Cortez-Winterourne Investigations for help in bringing the murderer of her brother to supernatural justice, a trap is sprung for Paige, Adam, Savannah and Lucas. Ava's (all-human) half-brother tried to cover gambling debts by betting on an all-sups fight-club and somehow paid with his life. Was he killed by one of the fighters, someone trying to drive that fight-club out of business, one of the fight-club owners or someone else? It's up to Cortez-Winterbourne Investigations to solve the mystery.
