It is said that enemies of Kino wear "masks" in their dealing with him in The Pearl.Discuss one character of whom this would be true, explaining...

It is highly ironic that the discovery of the Pearl of the
World as it is called in this text does not actually bring lasting joy and happiness to
Kino and his family It only brings eternal misery, which explains Kino's decision to
fling the pearl back into the sea. The effect of the pearl's discovery is clearly
remarked on by the author of this slim but powerful
novella:

The
news stirred up something infinitely black and evil in the town; the black distillate
was like the scorpion, or like the hunger in the smell of food, or like loneliness when
love is withheld. The poison sacs of the town began to manufacture venom, and the town
swelled and puffed with the pressure of
it.

One character who
immediately and incredibly hypocritically puts on a "mask" to cheat Kino is the Doctor.
His hypocrisy is perhaps worse because, having refused to treat his son, he suddenly
turns up at Kino's house, playing the role of caring doctor, even though Kino's son is
better. He therefore lies to devise treatment that is necessary for the patient and by
so doing gain some of the wealth from Kino. Even though Kino stands in the doorway as
the Doctor comes, with "hatred raging and flaming in the back of his eyes" he remains
frustrated by his lack of knowledge and his desire to protect his son. The Doctor
therefore would be a very good character to select as a wearer of a "mask" to trick
Kino.
