Billy Boyle: A World War II Mystery - James R. Benn
This book has a little bit of everything: mystery, action, adventure, double-dealing, and even some romance. I came across the book by happy accident, and now that I've read it, I'd like to complete the series. I had the killer pegged early on, but that didn't stop me from enjoying the rest of the story. I especially appreciated the protagonists crisis of conscience because it makes him seem more real. War is hell, indeed.
