"The roofs in Chicago are mostly flat and covered with either gray tar paper or hard black rubber. That is, unless the rooftop happens to be on the 3600 block of North Sheffield or the 1000 block of West Waveland. Then, of course, it is covered with bleachers, beer, and drunk baseball fans paying $200 a pop to watch the Cubs find new ways to lose baseball games.", [Michael Harvey, The Chicago Way]

And here's a tip. The book, Michael Harvey's "The Chicago Way," you can pick up from Barnes & Nobel in its digital edition for $1.99, here (hardcover, paperback, and audio also available). It's a detective story from the tough-guy school of Raymond Chandler, Dashiell Hammett, and Mickey Spillane, and a good one, and a steal at that price.

So if you've been wanting to fool around with digital books, here's your chance. (The software you need for reading it, also free, is here.)
