Bradley, Ryan, and Davis, Private Investigators was the most unique detective agency in Philadelphia, because Kevin Bradley and his partners, Evan and Lily, were not the mere mortals they appeared to be. Brad and Lily were powerful demons, and Evan was Brad's half-demon/half-mortal son. Solving earthly crimes ought to have been a cinch for them. But when someone began stealing the crystal balls which had belonged to the centuries-dead Dowager Empress of China, Brad and Evan found themselves hard-pressed to track the criminal mastermind down. For the thief was a dangerous -- perhaps unstoppable -- adversary...even for those with powers beyond anything known in the mortal realms.
