Query: Everyone knows everyone

Block ranks right up there with other writers who just know how to write (others include Ed McBain and Donald Westlake) . Dialogue and the ability to keep us needing to turn the page are the hallmarks of all of Block's works. Block sets up impossible to figure situations and manages to sort it all out. Be prepared for everything that happens to be somehow interconnected, I don't know how he does it. As Block puts it, "Coincidences are God's way of letting us know He is up there." Warning: try to read in no more than three sittings, you'll never keep it all straight.
