The Doomsday Conspiracy is very different from Sheldon’s other works. Sheldon’s stories usually feature a strong female protagonist, with a rags to riches story and twists & turns on every page. This one however, is a thriller with shades of science fiction (sort of) with the CIA, spies & UFOs all thrown in the mix.

The story concerns an American naval officer Commander, Robert Bellamy of the US Naval Intelligence, dispatched on a top secret mission. A weather balloon carrying sensitive

عده ای جهانگرد به طور اتفاقی شاهد ماجرایی میشن. اما طبق توافق کشورهای جهان کسی از مردم نباید از اون موضوع آگاه بشه. بنابراین یک جاسوس خبره فرستاده میشه تا تک تک شاهدان رو پیدا کنه. طبیعتا خود جاسوس به عنوان آخرین شاهد باید حذف بشه.

Several years before the X-files movie, Sidney Sheldon (writer of "I Dream of Jeannie") wrote this thriller about aliens and government cover ups.

It's pretty silly over all. What was weird, though, is that Sheldon includes a bunch of real evidence of a government conspiracy in the book's postscript (dozens of scientists who worked on Reagan's Star Wars who mysteriously died).

Moral of the story: Don't read books off of your mom's bookshelf even if you're really bored.

The Doomsday Conspiracy is another thriller novel by my favorite author, Sidney Sheldon. The story concerns an American naval officer, Commander Robert Bellamy who was mysteriously recruited in the NSA to investigate a balloon crash accident in the Swiss Alps where it said that there were seven (7) witnesses. He was tasked to search for the said witnesses and report it to the authorities immediately. I know I shall not go into the story in detail as it will contain spoilers but, personally I kin ...more

The plot is indeed captivating. But Mr. Sheldon didn't do his homework on the USSR. The book swarms with American stereotypes about the Soviets. Bad Russian sweets, he says - bullshit, you should have tasted some before making statements like that. I don't want to list all those errors and provocative paragraphs in The Doomsday Conspiracy, yet the book had been written long after the end of the Cold War. Well, it's a work of fiction rather than a documentary, but still it looks like a cheap prop ...more

"Juízo Final" tem todo aquele clima já saturado do cinema moderno que envolve espionagem e contra-espionagem, muita ação, reviravoltas inesperadas e missões "top-secret". Mesmo que estejamos vivendo em uma época que já está saturada com filmes dessa temática, Sheldon (que provavelmente foi um dos responsáveis por criar esse estilo de filme) consegue criar uma história extremamente envolvente e diria mesmo brilhante para a época em que foi escrita.

The Doomsday Conspiracy by Sidney Sheldon was a real entertainer! The author’s style of writing is what I enjoyed the most, it was simple, clear, witty at times and fast paced too! One could easily relate to all of his characters , specially the protagonist Commander Robert Bellamy, the portraying of that character was very real and convincing, thank god he was not one of those picture perfect super hero who knew everything! Other than that the plot was very gripping with enough twists and turns ...more

Sidney Sheldon's macho side. He is known for having female protagonists in his novels but this one is, as far as I know, the only exception, and it's not even a bad one for he did a good job. I thought this was going to be all sci-fi and boring but he sure proved me wrong. It was indeed very informative and I just couldn't put it down. I still can't touch a plant now without the scare that I might be hurting it. It had been an interesting journey, reading this book, and I sure will be doing

Commander Robert Bellamy is hired by the NSA to locate people that have witnessed a weather balloon, with some secret equipment, crash in the Swiss alps. They don't tell him why, and he soon realizes there is something big going on. It’s an interesting story and has much potential. Unfortunately, the big mystery culminates in a chase. Bellamy’s mission is to find the witnesses, but I would be more interested in the big discovery in the mountains if I were him. Bellamy’s search for the witnesses ...more

I got to 23% before I gave up. That's 66 pages I read today. I could probably have finished it by tonight. However, I just couldn't force myself to do so. Let me tell you why.

Spoiler Alert. Don't read if you plan to read this book.

The characters were thinner than the electronic pages I was reading from. They are so unbelievably wispy and ridiculous that I couldn't even move past them to forgive the low-hanging fruit of a story line. For instance: a man is driving to work when he sees a woman on

The first thing that struck me while I started to read this book is that this book has inspired an Indian Tamil language film named 'Thegidi' which I watched recently before reading this book. As I had watched the movie everything in this book was familiar and I was able to guess who was the antagonist (even if I hadn't watched the movie).
Yet this book was the best thriller book I have ever read because I get bored in every thriller book at some point. This was the only book that didn't bore m

This is by far the best book i've ever read. This book is filled with non-stop action and suspense. This novel takes place in modern day america and other parts of the world were they have spotted UFO's and a US Spy is sent to kill all who have seen them. It also has a interesting love story between two spies. The ending features the Aliens saying all the mistakes we've made and why they want to kill us all.

Antara novel dalam bahasa Inggeris yang awal dinikmati. Membantu dalam membuka koridor pengalaman membaca. Seingatnya jalan cerita yang rancak dengan espianoge (dicampur dengan Extraterrestrial?). Kini hanya beberapa adegan yang diingati termasuk assassination watak jurugambar dengan berpura-pura mahu mengambil gambar pasport. Apabila difikirkan balik terasa kurang masuk akal sebenarnya.

A decent novel, but, it lacks the quirk and suspense of the earlier novels like Bloodline, Windmills of the Gods, The Sands of Time and others. The plot is a little hackneyed, with a blend of science-fiction, and espionage stuff imbued in the story. There are assassinations, a brutal and powerful organization, aliens, etc, which makes it fascinating, but, the story somewhat lacked the intelligent ingenuity in terms of narration.

I am not much of a fan of SciFi stories. However, I find spy stories more engaging. Fortunately, Sidney Sheldon’s Doomsday Conspiracy provides us a generous helping of the two and tells us an exciting tale of cover-ups and betrayal. Robert Bellamy, a US intelligence agent, gives us a tour around the world as he tracks down witnesses to an extraordinary event in the Swiss Alps. As the story unfolds, we discover that it is more than extraordinary, as it is handled by obscure powers working in the ...more

I did enjoy this book. The usual twists and turns Sydney Sheldon creates (although a little predictable this time). It lost a star as I was disappointed with the abrupt odd end.

Another one of those one-day reads. It gets mildly interesting during the 'Hunted' phase; Jason Bourne and John Wick came to mind. Poor aliens didn't deserve to be a part of this. I dare you to read it with a straight face.

Sidney Sheldon (1917-2007) was an American writer who won awards in three careers—a Broadway playwright, a Hollywood TV and movie screenwriter, and a best-selling novelist.

His TV works spanned a twenty-year period during which he created I Dream of Jeannie (1965-70), Hart to Hart (1979-84), and The Patty Duke Show (1963-66), but it was not until after he turned 50 and began writing best-selling no
