I'm writing a spy thriller and I wanted to know if this seemed like a plausible way to advance the plot. The spy as infiltrated the targets home, and comes across a situation where he could recruit the daughter to help him (give him important information). Now the spy talks to the daughter and realizes that she may know something about his target. My question is, does this sound unrealistic? Is it a leap in logic to assume the daughter of his intended target might know something? Remember, he's making an assumption when he first realizes who she is. He doesn't know if she knows anything that's valuable to him. Lucky for him it works out. I'm wondering if readers will find that situation realistic? Would they laugh it off as a situation that's highly unlikely?
