Dark Fissures

Rick Cahill is a man cornered from every direction — a murder charge building against him with no body to prove it, a bank closing in on his home, and a police chief who has made him a personal mission. When a grieving widow hires him to investigate what she insists was her husband's murder rather than suicide, Rick takes the case for purely financial reasons. What he finds pulls him deeper into something far more dangerous than he bargained for, and the line between client and suspect, between love and manipulation, blurs in ways that could cost him everything he has left.

Coyle writes Rick Cahill with a particular kind of weathered moral seriousness — this is a protagonist who knows exactly what his flaws are and watches himself repeat them anyway. The plotting in Dark Fissures is tightly wound, layered with institutional corruption and personal betrayal that build pressure gradually rather than through blunt force. The San Diego setting feels lived-in rather than decorative, and the prose moves with the confidence of a writer who has found his character's voice completely. It's the kind of noir that earns its shadows.
