Incomplete question. However, I assumed you are referring to the series called "Alphas" by Zak Penn.
Explanation:
In that series, Nina was one of the main character in the series who had special super hero abilities, such as been able to read lips, as well the ability to coerce others, etc.
To resolve the crime, Nina using her lips reading abilities, completely heard the conversation going on between the store manager and the robbers, this was key in helping her to solve the crime.
