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 militar

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 line came from a legend about a hunter who was relating an experience he had on safari. “This huge lion was racing toward me, and all my gun bearers had fled. I had no gun, and there was nowhere to hide. Not a bush or a tree in sight. And the beast was charging straight at me, coming closer and closer.”

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

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 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

I have been a huge fan for years. I was saddened when he passed away as he is definitely one of my favorites. I haven't read any of his work for a few years and I was really in the mood for it today. I love how his books just draw me in and don't let go. This book was constant action. The reader is brought along on a thrilling political adventure. Poor guy doesn't know who to trust and how far these people are willing to go to keep the status quo. I would have loved if there had been a sequel to ...more

This book follows the story of Commander Robert Bellamy of US Naval Intelligence who is suddenly asked to handle a very secret mission with the help of no one. The only thing Robert knows about this mission is that there's an accident with a crashing weather balloon that carries sensitive military information in Switzerland. Therefore, Robert needs to find all the witnesses so that they can all be sworn to secrecy. However, things start to get weird since then. All the witnesses admit th

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

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

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

Well the book was just another Sidney Sheldon's work. Like many other Sheldon's books it stated with solving a case/puzzle and at the end of the 1st half there was a huge twist. Then the book was followed by one twist after other. At the end of the book all the mystery were solved in very few pages.

This is the one thing i don't like about Sheldon's book. In the end it feels like "Is that all! Nothing else is to be told?" I wish there were few more questions answered. The end was not as satisfyin

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 have to admit that I have tried many times to finish this book,but for some reason I have never been able to.

I'm very happy that, I do not own this book.

The thing with me is,if a book doesn't immediately grab me then I usually won't finish. The way I see it, I know how important it is to have a good and interesting beginning to a story, and if the author is unable to even make the first 20 pages interesting then that means the rest of the book probably isn't going to magically get better.

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.

Hold me suspense for hours and then it just plummeted to the ground. The ending sucks. I'm not fond of alien.
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.

Sheldon subtly brings about the issue of environmental hazards acros

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
