Cholera is killing Soho. The Board of Guardians blames the foul air. You are Dr. John Snow, and you suspect the water. The evidence will not all point the same way.
Tap places and pumps on the map to investigate. You have two visits a day.
The Registrar shows where the dead lived.
When you are ready, ask the Board to remove a pump handle. They will push back. Answer them with your evidence.
