Much of the L. A. Noire is based on interrogations. Even when it seems to you that someone is telling the truth, it may actually be a lie. This could ruin your final evaluation.
Steps
Step 1. Make sure you know what kind of questions you have
For example, the phrase "Possible Suspicions" in the notebook will ask the person questioned if they know of any possible suspects. The question may not be asked immediately, Cole may in fact ask "Do you have any suspicions?", Followed by an answer, and then "What do you think of Mr. Cavanagh?". You can't find the complete questions in the notebook.
Step 2. If the question is not asked immediately, try to take advantage of it
Pay attention to the answer of the person being questioned: the way they answer this question must be the same as they will use in the answer to the "true" question.
Step 3. Pay close attention to the suspect
If you notice him hesitating, looking away, or fidgeting, he is probably lying.
Step 4. Also pay close attention to what the suspect says
For example, if a purse worth $ 100 has been stolen, and the suspect talks about $ 50, it means he is lying.
Step 5. If you think a suspect is lying, check your notebook first
If you have evidence that the person is lying, click the "Lie" button. If you have no proof, click on "Doubt".
