The Black Echo:For LAPD homicide cop Harry Bosch - hero, maverick, nighthawk - the body in the drainpipe at Mulholland Dam is more than another anonymous statistic. This one is personal.The dead man, Billy Meadows, was a fellow Vietnam "tunnel rat" who fought side by side with him in a nightmare underground war that brought them to the depths of hell. Now, Bosch is about to relive the horror of Nam. From a dangerous maze of blind alleys to a daring criminal heist beneath the city to the torturous link that must be uncovered, his survival instincts will once again be tested to their limit.The Black Ice:Narcotics officer Cal Moore's orders were to look into the city's latest drug killing. Instead, he ends up in a motel room with his head in several pieces and a suicide note stuffed in his back pocket.Years ago, Harry Bosch learned the first rule of the good cop: don't look for the facts, but the glue that holds them together. Now, Harry's making some very dangerous connections, starting with one dead cop and leading to a bloody string of murders that winds from Hollywood Boulevard's drug bazaar to the dusty back alleys south of the border and into the center of a complex and lethal game - one in which Harry is the next and likeliest victim.
