Yikes! I read this on one day, and I read at only half the speed required for success in college, or so I was told back in my youth. Well, it was short, but also compelling. Not something one could easily put down once begun. Cain is a good author, if you like noir-y kinds of things. This is about as noir-y as it gets. A nice change from the heavier kinds of things I'd been reading.
So, an insurance agent, Walter Huff, makes a call on a client, Mr. Nirdlinger, who isn't home. Nirdlinger's wife, Phyllis comes down to meet Huff, and Huff is immediately smitten. Together they hatch a rather convoluted plot to insure Mr. Nirdlinger against accidental death with a double indemnity clause that kicks in should the accident occur in specific ways, such as being killed by an accident on a train. So, we get lots of plotting and practice.
Then, it seems, Phyllis has a 19-year old step daughter, Lola. Huff becomes rather enamored by Lola. Lola has a boyfriend, Nino, who may or may not be a sketchy character. Apparently, he is finishing up his Ph.D. in chemistry, but there are other things about him which may or may not be savory. Suffice to say the Nirdlingers did not approve of the alliance in the least.
Well, I could go on, but I can't write a plot summary nearly so well as Cain can write and flesh out the plot itself. One would be best to head for the nearest library, or book store if you prefer, and snag a copy. This is a true gem one should not miss.
