The phrase "If you lose, there's the devil to pay" suggests that losing or failing in a situation can lead to serious consequences or trouble. It emphasizes the importance of winning or succeeding to avoid negative repercussions. This expression can be applied in various contexts where the stakes are high, and failure could result in significant penalties or difficulties. In the book "The Forbidden Game" by L.J. Smith, this quote reflects the intense nature of the stories and the consequences faced by the characters when they face challenges or make risky decisions. It underscores the idea that failure often comes with a cost, and the characters must be prepared to deal with the repercussions of their actions.
