When Harry Bosch—former hero cop bumped from the L.A. homicide desk to the lowly Beverly Hills squad—gets the call on a death at Mulholland Dam, he recognizes the corpse as that of a fellow soldier in Vietnam. Together they had searched for Viet Cong in burrows beneath Vietnamese villages, and had both experienced the "black echo" of their own panic reverberating in their ears. Further investigation connects his old pal to an unsolved bank job—storm drains tunneled into the bank vault. When Harry and beautiful FBI agent Eleanor Wish uncover the connections between Vietnam and the bank job, both are put in danger by deadly ex-Marines and a powerful insider from either the LAPD or the FBI itself.

Michael Connelly is the author of Blood Work, Chasing the Dime, The Poet, Void Moon, and the Harry Bosch novels, which include The Black Ice, City of Bones, The Concrete Blonde, A Darkness More Than Night, and Lost Light. He lives in Florida.
