Messalina, Locusta, Lucretia, Theodora, they step aside in this particular review of peccant women. Cleopatra, supposed to have poisoned slaves in the spirit of scientific research, or perhaps as punishment for having handed her the wrong lipstick, also is set aside. It were supererogatory to attempt dealing with the ladies mentioned in the Bible and the Apocrypha, such as Jael, who drove the nail into the head of Sisera, or Judith, who cut off the head of Holofernes. Their stories are plainly and excellently told in the Scriptural manner, and the adding of detail would be mere fictional exercise. Something, perhaps, might be done for them by way of deducing their characters and physical shortcomings through examination of their deeds and motives--but this may be left to psychiatrists. There is room here merely for a soupcon of psychology--just as much, in fact, as may afford the writer an easy turn from one plain narrative to another. You will have no more of it than amounts, say, to the pinch of fennel that should go into the sauce for mackerel. Toffana, who in Italy supplied poison to wives aweary of their husbands and to ladies beginning to find their lovers inconvenient, and who thus at second hand murdered some six hundred persons, has her attractions for the criminological writer. The bother is that so many of them have found it out. The scanty material regarding her has been turned over so often that it has become somewhat tattered, and has worn rather thin for refashioning. The same may be said for Hieronyma Spara, a direct poisoner and Toffana's contemporary. The fashion they set passed to the Marquise de Brinvilliers, and she, with La Vigoureux and La Voisin, has been written up so often that the task of finding something new to say of her and her associates looks far too formidable for a man as lethargic as myself. In the abundance of material that criminal history provides about women choice becomes difficult. There is, for example, a plethora of women poisoners. Wherever a woman alone turns to murder it is a hundred to one that she will select poison as a medium. This at first sight may seem a curious fact, but there is for it a perfectly logical explanation, upon which I hope later to touch briefly. The concern of this book, however, is not purely with murder by women, though murder will bulk largely. Swindling will be dealt with, and casual allusion made to other crimes.
