Ravnica: City of Guilds (Magic: The Gathering: Ravnica Cycle)
Lieutenant Agrus Kos enjoys his work. A top-notch officer of the city guard, he's been on the force over fifty years. He works alone. And the League of Wojek never had problems with him or his worrk. Until now. They gave him a partner to train, who promptly got himself killed. And the more he looks into the death the less he likes it. Something dard is moving within the guilds of Ravnica.
