The Man with Identical Teeth

Description of the book The Man with Identical Teeth:

In a small Californian town, where real estate agent Leo Ransible has recently settled, there is nothing interesting: only neighborly gossip, family squabbles, racism, and a dilapidated plumbing system. However, sometimes a school teacher, engaged in amateur excavations, finds obsidian arrowheads of the Native Americans.
Time passes, a domestic conflict smoothly turns into a hidden enmity, and when ancient remains of a Native American settlement are found on one of the plots intended for development, a neighbor decides to play a cruel prank on the hated outsider. But the joke uncovers a problem that threatens all the residents of the county. The locals turn a blind eye, and only the outsider Leo is ready to fight.
The novel describes the town where Philip K. Dick himself lived during his creative prime, with his friends and neighbors serving as prototypes for the characters.
