In Evan Hunter's 1954 novel Don't Crowd Me an NYC advertising copywriter seeks tranquility in the lake region but instead finds himself encountering two sisters with very different temperaments who both seem to find him irresistible. Then, of course, there's a murder to spoil everything, and it looks like he's the only one who can solve it. The plot may sound improbable, but Hunter, born Salvatore Albert Lombino, was better known by his pseudonym Ed McBain, which means you would expect this to be decently written. And in fact you would be correct. The cover art, which is great, was painted by Walter Popp. 

It's a good thing the real world isn't like the worlds of pulp and mid-century crime fiction. In those realms, when a woman receives an unexpected visitor the result is often disastrous. Bad cops, evil crooks, ruthless blackmailers, lecherous uncles, and all sorts of nasty characters usually await on the other side of the door. Above and below you see a collection of mid-century paperback fronts showing those fraught moments just after a woman opens her door to trouble, or trouble takes matters into its own hands and busts its way in. Our recommendation: in the event of an unexpected knock just go out the window.

Today we have another cover collection for you. We had noticed quite a few pieces of pulp/sleaze art featuring syringes as a central element, so we’ve gathered up twenty examples, with art by Michel Gourdon and others. Some of these are from Flickr, so thanks to the original uploaders.
