I went on a long walk a few days back, and took a gajillion photos... but I'm lazy and slow in getting them up. Soon.
In the meantime:
#4 -- "Whiskey River" by Loren D. Estleman
I first read this during my hard-boiled heyday, when I was 19 or so, and was pretty disappointed -- later I read all the rest of his Detroit history books, liked them considerably more, but never gave this a second chance.
Now, finally. I'm not sure why I wasn't thrilled with this way back when. Maybe not enough mystery? It's set in Prohibition-era Detroit, telling the story of competing bootlegging gangs through the eyes of a journalist who's a bit too close to all the unsavory goings-on. It was the first of a trilogy on crime through Detroit's 20th-century history, mixing real-life tales with fiction -- last I knew, the trilogy had expanded, Hitchhiker's-style, to about six books. I'll probably go back and reread them in the coming months, since I remember liking all the rest more than this one, and this time 'round I liked this one quite a bit.
