Celebrated Crimes by Alexandre Dumas Celebrated Crimes

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 careful, mature reader, for whom the books are intended, will recognize, and allow for, this fact.The first volume comprises the annals of the Borgias and the Cenci. 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...

Is Mars Habitable? by Alfred Russel Wallace Is Mars Habitable?

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.

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...

Storm Over Warlock by Andre Norton Storm Over Warlock

The Throg task force struck the Terran survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. Eye-searing lances of energy lashed back and forth across the base with methodical accuracy. And a single cowering witness, flattened on a ledge in the heights above, knew that when the last of those yellow-red bolts fell, nothing human would be left alive down there.
