This is a very entertaining book that tries to stick fairly closely to the facts. Subsequent reading leads me to believe that he may have relied primarily secondary sources. Even so, I would quickly suggest this book as informative, intelligent, and fun reading. Mr. Harris also goes into some detail about some other missing ships and sailors (such as the Erebus and the Terror, used in early Polar exploration), and delves into the history behind the explosion (or attack) on the Maine.

SS Waratah
I haven't finished this one yet. However, my first impressions are that it is more thoroughly researched than Without a Trace, but less entertaining. I also did not care for the organization of the article on the Waratah. I'll hold back my full review until I've finished.

The Bermuda Triangle.
This book lays out a number of mysterious phenomena, not just mysterious disappearances, and is very entertaining, yet factual. It is a survey of the phenomena without providing a (supposedly) definitive explanation, with some exceptions, such as the Bermuda Triangle. Mr. Clark, who used to work with the respected J. Allen Hynek, the UFO researcher, does seem at times to be a little more credulous than I would like, though he is no more at fault for this than the militant skeptics are for being so rabidly rationalist. For example, he faults skeptics for ignoring eyewitness testimony, often reducing it to misperception or hoaxing on the part of the observer. However, when considering such phenomena as the Loch Ness Monster, he basically ignores the fact that many descriptions of the monster are violently inconsistent, which would lead one to at least consider that there are problems, to say the least, with these eyewitness reports. (It should be noted that this seems to be an epidemic among UFO researchers, at least the most vocal ones.) This fault (in my perception) notwithstanding, I highly recommend this book. At minimum, it will provide a good laugh, hopefully, it will make you think.
