Joan Williams has just moved to the city with her husband... But not for long. This case is her top priority, and she isn't letting the lab take on anything until this one is closed.
After she is framed for the murder of her fiancé, Zahara Jeri is given a chance by her would-be father-in-law to prove her innocence and find the real criminal. She suspects the criminal is one of the man's children, her fiancé's half-siblings. Because she has no evidence, she has to try and force out a confession. And she has to do it in 24 hours.
