The Motive: Cycle of Violence by Joseph Badal
Good plot about an Albuquerque doctor who’s called to Hawaii upon the death of his sister. He doesn’t believe it’s a suicide, as the police claim, and sets out to prove it. Along the way, he meets a woman his sister worked with to help kids, and when they’re both threatened, enlists the aid of a former pal. My only gripe is the novel spends too much time on the bad guys’ stories and also drags out the ending – which segues to the next book in the series. Still, it was full of action and adventure, tension and plot development and several great characters.
