Walkthrough

1. To start the quest, talk to the guard outside the mansion. He tells you that Lord Sinclair has been murdered. Tell him that you’ll help.

2. Enter the mansion, go to the room in the east, then north. You should now be in a room with a dagger, a pot and a smashed window.

Investigate the smashed window, and take the Pungent pot and Criminal’s Dagger.

3. Go outside the house, and go to the west of it, where the dog is. Investigate the Sturdy wooden gate.

4. Now, go out of the gate to the south, and follow the road to the south until you see a Gossip. Talk to him, and ask him who he thinks was responsible. He tells you that the Poison Salesman made a big sale to one of the Sinclair family members.

5. Get to the bar at Seer’s Village, you will see the Poison Salesman. Talk to him, and ask him who he sold the poison to. He tells you that he managed to sell a bottle to each of the Sinclairs. Then, show him the Pungent pot you found earlier in the quest.

6. Head back to the mansion, and talk to each of the children that bought the poison: Bob, Anna, Frank, David, Carol and Elizabeth. Ask them about the poison. After you talk to each of them, investigate each of the places they have told you they used the poison on:

Bob – Beehive. It is located where the cows are.
Anna – The compost, which is west of the entrance of the house.

Frank – Family Crest on the southern wall of the house, east of the entrance.

David – Spider’s Nest upstairs, in the southern part.

Carol – Drain outside the house, on the western part of the southern wall.

Elizabeth – Fountain in the eastern part of the garden.

There is one place where there’s no poison used. This means that one of the persons you asked are lying.

Bob – Beehive. It is located where the cows and chickens are.
Anna – The compost, which is west of the entrance of the house.

Frank – The Sinclair Family Crest on the southern wall outside the house, east of the entrance.

David – Spider’s Nest upstairs, in the southern part.

Carol – Drain outside the house, on the western part of the southern wall.

Elizabeth – Fountain in the eastern part of the garden.

7. The thread you took earlier in the quest has the same color as your culprit. You will now need to find the barrel that belongs to your culprint. Two are downstairs, and the rest are upstairs. You know the name of the person owning the barrel, since each barrel has it’s own name. You will find an item hidden in the barrel.

8. Go out the house and go to the room at the north-western part of the house (the entrance is outside). Investigate the sacks, and you will find some flypaper. You will need 2 of them.

9. Go inside, to the Cook’s room, which is located north-west in the building. Take from the barrel of flour. Use some flour on the Criminal’s dagger. Then, use the dagger on a flypaper. Take some more floor, and use it on the object you found earlier, in the barrel during step 7. Then, use that object with a flypaper. Use the two fingerprints with each other, and you will find that they match exactly.

10. Go outside again, and talk to the guard where you started the quest. Tell him that you know who did it. You will show all evidences, and then you will complete the quest. Congratulations!
