The Narrows - Michael Connelly

Sod's law in operation as far as the timing of reading this Harry Bosch novel goes.... I'd already picked up that The Poet tells a key event in Harry's life and career but I'd not been able to find it at the library, and it turns out that The Narrows is, in effect, a sequel to The Poet. Anyway, The Poet will make interesting reading when I do lay my hands on a copy.

The key players are the serial killer known as The Poet, ex cop private eye Bosch and FBI agent Rachel Walling. As the FBI investigate a mass grave in the Nevada desert, Bosch and Walling are lured, by separate means and with differing motivations, towards the same spot - but the climax takes place back in Harry's LA heartland.
