Duluth - Vegas - Philadelphia

Brian Freeman has written a rather clever thriller called "Immoral". The new detective is Jonathan Stride of Duluth (not a usual venue in detective novels) , ends up meeting a girl cop in Vegas (a rather common venue, at least on TV) and I guess that he (and she) will be back for more. This was one I enjoyed while I was reading it - but can't remember much of the story. A good airplane book perhaps.
A second book about Kevin and Jessica in Philadelphia is "The Skin Gods" by Richard Montanari. Kevin, who got shot at the end of the last book, is back for more punishment and Jessica is looking at a ESPN2 boxing match. As the book above, not real memorable but it kept me reading.
