I remember the men's magazines growing up. True Crime and all of that. Couldn't just pick them up and look through them when I was a kid or the drug store owner would chase me out. The trick was to take a legit magazine like some sports mag and lay it on top of the trashy men's magazine. Then I'd reach down and pretend to leaf through the sports mag only my fingers would go past the first magazine and catch the pages of the second one. If the guy behind the counter looked over, he'd just see the top cover and not realize I was looking at the one beneath.
I wrote a novel called Rearview trying to capture the illicit feel of those old True Crime magazines and Mike Hammer and the hard boiled detective stories. Have to dust it off and put it out here.
