After reading Pocket-47 I was sure Nicholas Colt couldn't be put through more misery than he went through already. This novel proves me wrong, very wrong.
When the MO of his old enemies from the cult Harvest Angels is used in another few killings Colt decides to investigate. He ends up being captured and brainwashed and involved in an evil plot larger than anything I've read in PI fiction. It's very, very dark and the punishment Colt is forced to take sometimes made me stop reading, just to take a breath and not be enveloped totally in it's darkness.
