An execution and terrorist threat lie at the heart of this brilliant thirteenth Harry Bosch novel from the award-winning No. 1 bestselling author Michael Connelly.

When a physicist is murdered in Los Angeles on the overlook above the Mulholland Dam, a site with a stunning view over the city, it seems the killer has no fear of publicity. And when it's discovered that the victim turned over a quantity of a lethal chemical to his killer before he died, Harry knows he has more than just a single death to worry about.

Plunged into a vortex of conflict between the LAPD, FBI and Homeland Security, Harry realises the clock is ticking and he must solve the murder or face unimaginable consequences.
