Homicide detectives Liv DeMarco and Brad Fennel have one of the best closure rates in the department, but this case has them stumped. Will they figure out who had means, motive, and opportunity, or will the killer actually get away with murder? People aren't supposed to fly, so when a woman crashes into the roof of a car parked outside an exclusive hotel, the first thing Detective Liv DeMarco has to determine is if she jumped or if she was pushed. A party was raging on the roof at the time of the alleged murder, so finding witnesses shouldn't be that difficult. Someone must have seen the woman go over, but no one's talking.

To complicate matters, a call from Axel Kincaid has Liv second-guessing everything. Kincaid has information concerning the woman and the party guests. But what he has to say doesn't make a lot of sense.

Unsure what or who to believe, Liv and her partner Brad will have to reconstruct the scene and piece everything together bit by bit, but nothing is as it seems. And when half the suspects also have motive and opportunity, it might be impossible to determine exactly what happened on that roof and who is to blame.
