I'm a bit blocked on a scene. I've rewritten it twice, but I'm still not happy with it. I think it's because my sleuth character is coming across as too much of a wimp. She's supposed to be a cool and collected Sherlock Holmes type. However, she's just discovered that everything she's been told up until that point in the novel by someone she trusts is a complete lie.
The situation itself is complicated, but I'll try to come up with something close:
Suppose you're in a car with your sainted older brother. He makes a wrong turn and you're carjacked. In addition, the thieves demand a ring from him that belonged to your grandfather. You talk to the police, but he is too shaken to speak. For the few days he's changed for the worst, constantly on the phone screaming at the insurance company to cut him a check. You keep asking for a case number to follow up for him and he won't give you one and yells for you to get off his back.
A few days later you're in a pawnshop and you see your grandfather's ring. You ask to see the footage of the man who brought in the ring. It's your brother.
How do you react when you recognize him on the footage? How do you react when you learn he was screaming at a phone with nobody at the other end? You don't want to make a scene and send your brother to prison, but you have a lot of questions and you are gutted by this deception.
