Above, a fun cover for Al Fray's And Kill Once More, published in 1955, about a lifeguard turned bodyguard who gets involved in murder. The cover art on this is by Saul Levine, who you can see more of here and here. 

You ever stay in a place and the internet sucks? It happens to us all the time. The amenities are also sorely lacking at Guido d’Arpino's San Francisco rooming house, but at least his daughter Emma is sexually available to most of the guests that roll through, including touring saxophonist Harry Purcell. Their involvement produces an unexpected customer bonus: pregnancy! The impending arrival of the little d’Arpino sets into a motion a series of events that leads to murder. Since the story is told in flashback at Harry's trial, none of this is a surprise, but the details of how he ended up in the dock are interesting, and in the end the lesson of this Prohibition era tale is clear—never get involved with a musician. And we say that as musicians. We're the worst. Pretty good book, though. In the same way San Fran exteriors are used in some of the best mid-century noir movies, author Fred Malloy (a pseudonym too involved to work out on a perfect beach day, sorry), uses San Fran specificity to spice this one up. For people interested in the city, that alone probably is worth the price of the book. 1954 copyright on this edition, and cover art by Saul Levine.
