In Book #3, One Right Thing, we find that our sarcastic and stubborn retired homicide detective Marty Singer has taken a road trip, a holiday to recuperate from his recent cancer surgery. On the way back to Washington he drives through a sleepy town, and notices a massive billboard advertising a murder. If this wasn't odd in itself, the victim is someone that he arrested 20 years previously - and for those 20 years his conscience has been bothered, because something just wasn't right about that bust. Time to investigate - but the family doesn't want him there after finding out who he is, and the local police are hostile. Why does no one want him looking into this murder?

I enjoyed this book a great deal because it gives us some depth and insight into Marty's career 20 years ago, and also an ethical and moral look at the strain that those who deal with murder day in, day out are under, and the grey areas of crime and law enforcement. It has a redemption arc for multiple characters; and I felt provided more depth than the previous book, whilst also adding an interesting supporting cast that allowed to the story to take multiple twists and turns.

It was fast paced, with plenty of things that I wasn't expecting and I think is my favourite of the three books in this series I've read so far. I'd still recommend reading it in order just to get the full experience of Marty's journey as a retired detective battling cancer, but still unwilling to give up on crimes that he can help with. Definitely looking forward to the next one.
