‘Curiouser and curiouser’ – fascinating mysteries to explore

Author Bill O’Neill has authored many books on Trivia and is an expert in this field! His topics include movies, football, baseball, wars, rock music, simply random trivia facts, US States, famous events in modern history, and unexplained mysteries. With a nod to providing interesting reading material while passing the time at home, Bill offers a cascade of facts and stories that address curiosity while thoroughly entertaining.

Providing an overview of the topics of interest in this book, Bill outlines his content in the Introduction – ‘When it comes to unexplained mysteries, this book truly has something for everyone – history, science, the supernatural, and true crime…You’re read about mysterious lost treasures, such as the ancient Germanic warlord Alaric’s tomb and the possible location of King Solomon’s mines. Strange science mysteries are also covered, including the mysterious hexagon on Saturn and the bizarre blobs that fell on Oakville, Washington in 1994…’ Whose curiosity could resist?

In Bill’s casual but solid style of writing, he shares such fascinating mysteries as a blond hair blue eye South American tribe, the missing Romanov jewels, Victorian era UFOs, the mysterious Goodyear blimp, nuclear weapons test vs. something from another world, volcanoes an asteroid or both, the existence of Tardigrades (water bears – eight-legged segmented animals that usually only measure about a half a millimeter when full grown and can survive extreme radiation and outer space that no one understands), the unexplained Shugborough Inscription, and more.

Not only is the book entertaining – it is also very instructive. For those familiar with Bill O’Neill’s talent for tickling the brain, this book is a must read – one of his best. For those who are simply looking for solid entertaining reading to while away the hours, welcome to the field expert! Highly recommended – especially during these times…

This is a grab bag of interesting mysteries for just about anyone, delving into true crime, history, science, and the supernatural. The historical span is from ancient times to fairly recent. The author travels along with the mystery, trying to offer solutions or sharing the explanations derived so far. Generally, there are no solutions, just educated guesses. However, the author's writing style is interesting and readable.

There are lots of interesting historical tidbits to learn here but my favorite was regarding the Romans. Because of the shallow nature of their ships, the Romans sailed around the edges of the Mediterranean Sea, rather than sailing straight across. When they wanted to do naval battle, they tended to hire Egyptians, Greeks, and Phonecians to do the work.

This is exactly what it's billed as--a collection of delightfully wacky, bizarrely weird, oddly wondrous, and thrillingly whimsical unsolved mysteries throughout the years. It does not try and explain them, but rather provides the available theories and leaves it up to your imagination to fill in the rest.

I rather enjoyed this collection and found it a nice little escape for a few hours. A few of the stories I had heard of but by and far most were new to me. This was a pleasant surprise.

A fascinating short book full of unexplained mysteries from all over the world! However as soon as I got interested in a mystery, it was already over and on to the next one. Each one is only a few pages long leaving you wanting more. Plus, the longer ones seemed like a super boring history lesson, and not as much mystery.

Thought provoking

The mysteries might even be called myths. They spanned time and space itself. Some are farfetched but some resonated with me.
