Final answer:
The specific circumstances of Mehri's affair and its discovery by Marji's father are not detailed in the provided text, leading to an inability to accurately answer the question without the correct context from the relevant narrative.
Step-by-step explanation:
The question pertains to how the news of Mehri's secret affair was discovered by Marji's father and its consequences.
However, there seems to be a mix-up as the provided reference text does not directly disclose information regarding Marji, Mehri, or her father's reactions toward the secret affair.
Instead, these texts reference different storylines and dramas, including works by Henrik Ibsen and accounts of historical characters like Temujin from 'The Secret History of the Mongols'.
To answer such a question accurately, it would be necessary to refer to the specific source material or narrative that discusses the characters in question.
It appears the question is about a narrative situation, likely from a piece of literature, where clandestine affairs and their discovery play a crucial role in the development of characters and the plot.
