“The 509” is the eastern, more rural part of Washington state, where Spokane is the big town. I’d already read one of the books in Colin Conway’sThe 509 series, The Long Cold Winter, and liked it very much. So I picked up the first installment, The Side Hustle.

Quinn Delaney and Marci Burkett are homicide detectives in Spokane. When they’re called to view the body of Jacob Kidwell, online financial guru, they find him with his neck broken at the bottom of a stairway in his apartment building. It could easily be an accident, but the detectives suspect he was pushed. The suspicion is increased when they learn that one of his two computers has disappeared.

Young Kirby Willis, an Uber driver and budding entrepreneur, idolized Jacob, who was his friend, and can’t resist making his own investigation. In theory, the cops should resent his interference, but he has sources of information unavailable to them, and anyway, Marci thinks he’s kind of cute.

Quinn, meanwhile, is having trouble concentrating on his work because of personal problems that he won’t discuss with Marci. When he does finally open up to someone, it’s almost the last person you’d expect… but that could be the very person who can offer him hope.

Author Colin Conway excels at portraying three-dimensional characters. I liked Quinn, Marci, and Kirby very much, and followed their adventures with just as much interest as if the book had been a blood-and-thunder thriller. The Side Hustle has the added value of actually offering good advice for living, at no additional charge.

I liked The Side Hustle even more than The Long Cold Winter. I’m officially a fan of this series.
