This page offers a guide on where to locate and how to complete, The Doom Book of Cats, which is a Mystery located in Grantebridgescire, Assassin’s Creed Valhalla.
Getting Rid of the Rats
North of Grantebridge town, you’ll come across two farm houses, one is owned by a lady, the other by a man. The man’s land is swarming with rats and he needs Eivor’s help to clear them away so they don’t eat all of his wheat. After speaking to the man, you’ll need to head over and speak to the woman, whose house is just nearby. You’ll need to convince her to let her cats loose so they eat all of the rats. To do this, you’ll need at least a Level 2 in** Charisma**, which is earned through participating in Flyting contests. When you’ve convinced the woman, she’ll give you a key to her house, which you can then use to let loose all of her feline friends!
Once the cats are free, speak to the man again and tell him of your success. He will give you a key to his house as thanks. You can use the key to head into his home and take some of his goods. Within his home, you’ll find food, silver and supplies, and you’ll also earn 1,200 EXP.
