In the book of the Colombian novelist García Márquez Love in the Time of Cholera there is the following phrase:
She said: “Not even Jonah’s wife would swallow that story.”
I tried to find some information about Jonah's wife online but couldn't find anything. Could anybody please help me interpret this sentence? What is so special about his wife? Does the use of the verb swallow have anything to do with the fish that swallowed Jonah?
