Deadlier than the male - Douglas Skelton

Most killers are men. But never turn your back on a woman. Murder, madness and maliciousness abound in this hangman's dozen of she-devils. Culled from over five hundred years of bloody history by crime writer and journalist Douglas Skelton, these pages uncover the mad, the bad and the dangerous to know.
Vengeful Queen Joan, who made her husband's assassins pay a fearful price for their treason.
Beautiful Jean Livingston, who bravely faced The Maiden after murdering her abusive husband.
Child killers Helen Torrence and Jean Waldie, who sold their victim to anatomists.
Baby farmer Jessie King, who dealt in flsh... and death.
These cases, together with a host of others, prove that women are far from the gentler sex. Most killers are men. But women are more deadly.
