You live in Marshclan, a clan that lives in a small camp near a huge lake. Across from the lake, there's a twoleg city, so cats rarely go there. The main prey is fish and occasionally rabbits. But recently, the Marshclan deputy, Poppytail, was found dead near the border between the city and the Clan's territory. The murderer will choose someone to kill every two days. The med. cat(s) will also receive a clue every two days.
