Dumas's 'Celebrated Crimes' was not written for children. The novelist has spared no language -- has minced no words -- to describe the violent scenes of a violent time.In some instances facts appear distorted out of their true perspective, and in others the author makes unwarranted charges.

The name of the noted and notorious Florentine family has become a synonym for intrigue and violence, and yet the Borgias have not been without stanch defenders in history...

In 1907 Wallace wrote the short book Is Mars Habitable? to criticize the claims made by Percival Lowell that there were Martian canals built by intelligent beings. Wallace did months of research, consulted various experts, and produced his own scientific analysis of the Martian climate and atmospheric conditions. Among other things Wallace pointed out that spectroscopic analysis had shown no signs of water vapor in the Martian atmosphere, that Lowell’s analysis of Mars’ climate was seriously flawed and badly overestimated the surface temperature, and that low atmospheric pressure would make liquid water, let alone a planet girding irrigation system, impossible.

If it is possible to conquer space, then perhaps it is also possible to conquer time. At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long-forgotten secrets of the past. That was why young Ross Murdock, above average in intelligence but a belligerently independent nonconformist, found himself on a “hush-hush” government project at a secret base in the Arctic...
