"Doctor, I can't let you make a trip for nothing. This is the money that everyone has gathered. I hope you won't complain that it's too little."
The village chief handed a bag to Claud. There were notes of different amounts, estimated to be more than 500 dollars.
Sandra said, "Chief, you can keep this money. We don't need this."
Claud nodded and solemnly said, "Chief, this matter is not over yet. I told Marcelo that this is a synthetic poison, and some people did this to you. If you can't find the culprit, you will still be poisoned."
The villagers were in an uproar, discussing among themselves.
Claud gestured for everyone to be quiet and asked, "Only these people were poisoned, and the others were not. This means that these people have come to contact with the poison. Where have you all been?"
Everyone looked at each other and finally came to a conclusion.
They had all gone to the mountain behind the village.
