There's a lot I can't mention about the plot, as it's intricate, but cleverly done, and I wouldn't want to give away any spoilers. However, I loved Simon. He wasn't the cliché know-it-all PI, or the Jessica Fletcher who just-so-happens to have friends in all the convenient places. When Simon calls on an old friend, who happens to be in a position to know about crime/the investigation, that's naturally explained by his past as a crime reporter/investigator.
The romance is sweet, but neither a primary or secondary aspect of the plot. It's more in the background, with fade-to-black scenes mentioned in passing. Still, there's nicely explored chemistry and attraction between Simon and Cameron.
The investigation itself was clever, realistically slow, with logical sources, smart clues and misheard information. I loved how every character contributed something – Simon, Bill, Cameron, and even some minor characters who were able to offer influence, information, or even assistance without even being on page, in some cases. The end revelations and surprises were well written and took me by surprise. The way Bill and Cameron ended the book were both surprising, but offered intrigue for how the rest of the series will proceed. There are so many possibilities, for what might happen next.
