COMPUTERS / Database Management / General Lorimer Black - Young, Good-looking, But With A Somewhat Troubled Expression - Does Not Understand Why His World Is Being Torn Apart, Though He Does Know That For The Most Part It Is Made Up Of Bluster And Hypocrisy. His Business, Trying To Keep Insurance Companies From Paying Out The Money They've Promised, Is A Con Game Run With The Protection Of The Law. One Winter's Morning, Lorimer Goes To Keep A Perfectly Routine Business Appointment And Finds A Hanged Man. A Bad Start To The Day, By Any Standards, And An Ominous Portent Of Things To Come. Broad humor and bitter irony collide in this fictional autobiography of Rabo Karabekian, who, at age seventy-one, wants to be left alone on his Long Island estate with the secret he has locked inside his potato barn. But then a voluptuous young widow badgers Rabo into telling his life story—and Vonnegut in turn tells us the plain, heart-hammering truth about man’s careless fancy to create or destroy what he loves. A chronicle of this imaginary place, narrated by a skinny kid with wire-rimmed glasses who is raised as a straitlaced Protestant but is fascinated by the Catholic Church (he dreams of being burnt at the stake) and by the notion of a more exotic family background (he'd like to be called Keillorini). One winter morning Lorimer Black goes to keep a business appointment and finds a hanged man. This is just the start of what turns out to be a horrendous period for Lorimer as he realizes that he's being set up at work and cast adrift outside the office.
