When the widow of Terry McCaleb asks Harry Bosch to look into her husband's sudden death, the retired detective expects to find bad luck or a failing heart. Instead he finds the fingerprints of an old nightmare. McCaleb, the FBI profiler who once hunted the serial killer known as the Poet, may have been murdered — and the Poet, long presumed dead, may be very much alive.
Bosch's private inquiry collides with an official FBI hunt led by Agent Rachel Walling, the profiler whose career the killer nearly destroyed years before. Forced into an uneasy alliance and squarely at odds with the Bureau, the two follow their quarry from the desert outside Las Vegas to the concrete flood channels of Los Angeles, toward a place called the Narrows and a reckoning years in the making.
A direct sequel to Michael Connelly's The Poet, the tenth Harry Bosch novel pulls threads from Blood Work and A Darkness More Than Night into one of the series' most relentless manhunts.
