About this book
Some mysteries survive because the final piece of evidence never arrives. Others endure because witness accounts conflict, records disappear, technology reaches its limits or the most compelling theory still cannot be proved.
This wide-ranging collection revisits famous disappearances and unresolved cases including Amelia Earhart, Malaysia Airlines Flight MH370, D.B. Cooper, the Roanoke colony, Percy Fawcett, the Flannan Isles, the Zodiac Killer, Jack the Ripper and other cases that continue to generate debate.
Each mystery is approached as an investigation rather than a campfire story: what is established, what is disputed, which theories fit the evidence and which questions remain genuinely open.
What you’ll discover inside
✓
The evidence behind disappearances such as Amelia Earhart, MH370, D.B. Cooper and Roanoke.
✓
Why the Zodiac Killer, Jack the Ripper, Black Dahlia and other crimes remain unresolved.
✓

✓
How Dyatlov Pass, Tunguska, the Taos Hum and Hessdalen Lights resist one simple explanation.
✓
Which famous sea, treasure and historical mysteries are stronger after weak claims are removed.
