The Girl from Raven Island - Glenn Burwell

A police officer is murdered after a demonstration in Vancouver. Detective Robert Lui identifies suspects and travels to Raven Island, on BC's coast. He's looking for motive but finds danger. When more people are murdered, Robert realizes his assumptions about the case might be wrong, and he uses unorthodox methods to draw out an opponent. But his personal and professional mistakes are adding up. He's had better Octobers.
