La sombra

Robert Olmstead, on a mission to discover the identity of his distant ancestors, finds himself in rural Massachusetts.  On the tips of some of thepeople he meets, he decides to take a bus into Innsmouth.  The people he meets on the bus, and later in town, seem to look a little strange.  They havesloping foreheads, big lips, and bulging fishy eyes.  Once in town, he asks around and eventually hears rumors about the interbreeding of the citizens ofInnsmouth with fish-like creatures that came from the sea.  This story shakes Olmstead's nerves, but he eventually chalks it up to unfounded rumors andspeculation.

That is, until, the bus he hoped to take out of town before night fall breaks down, leaving his stranded in Innsmouth.  Olmstead is forced tosleep overnight in a run down hotel when the natives suddenly become hostile.  Olmstead must choose to either flee or run for his life but one this issure - what he discovers off the shores of this little Massachusetts town will alter his life forever.
The Shadow Over Innsmouth is unique from Lovecraft'sother works in that it partially abandons the theme of plausible deniability.  By the end of the story, a police investigation begins regarding thepeople of Innsmouth.  However, we don't know the result of the investigation...

I loved Innsmouth for two reasons.  One is the great "chase-scene" thatensues, in which Olmstead is certain that he will be killed if he is found.  The other is the ending, which I will let you read on your own - it's a doozie!
