In the case of the Peltzer brothers we have a man who is of good social position, falling desperately in love with the wife of a successful barrister. The wife, though unhappy in her domestic life, refuses to become her lover's mistress; marriage is the only way to secure her. So Armand Peltzer plots to murder the husband. For this purpose he calls in the help of a brother, a ne'er-do-well, who has left his native country under a cloud. He sends for this dubious person to Europe, and there between them they plan the murder of the inconvenient husband. Though the idea of the crime comes from the one brother, the other receives the idea without repugnance and enters wholeheartedly into the commission of the murder. The ascendency of the one is evident, but he knows his man, is sure that he will have no difficulty in securing the other's co-operation in his felonious purpose. Armand Peltzer should have lived in the Italy of the Renaissance.
The crime was cunningly devised, and methodically and successfully accomplished. Only an over-anxiety to secure the fruits of it led to its detection. Barre and Lebiez are a perfect criminal couple, both young men of good education, trained to better things, but the one idle, greedy and vicious, the other cynical, indifferent, inclined at best to a lazy sentimentalism. Barre is a needy stockbroker at the end of his tether, desperate to find an expedient for raising the wind, Lebiez a medical student who writes morbid verses to a skull and lectures on Darwinism. To Barre belongs the original suggestion to murder an old woman who sells milk and is reputed to have savings. But his friend and former schoolfellow, Lebiez, accepts the suggestion placidly, and reconciles himself to the murder of an unnecessary old woman by the same argument as that used by Raskolnikoff in "Crime and Punishment" to justify the killing of his victim.
In all the cases here quoted the couples are essentially criminal couples. From whichever of the two comes the first suggestion of crime, it falls on soil already prepared to receive it; the response to the suggestion is immediate. In degree of guilt there is little or nothing to choose between them. But the more interesting instances of dual crime are those in which one innocent hitherto of crime, to whom it is morally repugnant, is persuaded by another to the commission of a criminal act, as Cassius persuades Brutus; Iago, Othello. Cassius is a criminal by instinct. Placed in a social position which removes him from the temptation to ordinary crime, circumstances combine in his case to bring out the criminal tendency and give it free play in the projected murder of Caesar. Sour, envious, unscrupulous, the suggestion to kill Caesar under the guise of the public weal is in reality a gratification to Cassius of his own ignoble instincts, and the deliberate unscrupulousness with which he seeks to corrupt the honourable metal, seduce the noble mind of his friend, is typical of the man's innate dishonesty. Cassius belongs to that particular type of the envious nature which Shakespeare is fond of exemplifying with more or less degree of villainy in such characters as Iago, Edmund, and Don John, of which Robert Butler, whose career is given in this book, is a living instance. Cassius on public grounds tempts Brutus to crime as subtly as on private grounds Iago tempts Othello, and with something of the same malicious satisfaction; the soliloquy of Cassius at the end of the second scene of the first act is that of a bad man and a false friend. Indeed, the quarrel between Brutus and Cassius after the murder of Caesar loses much of its sincerity and pathos unless we can forget for the moment the real character of Cassius. But the interest in the cases of Cassius and Brutus, Iago and Othello, lies not so much in the nature of the prompter of the crime. The instances in which an honest, honourable man is by force of another's suggestion converted into a criminal are psychologically remarkable. It is to be expected that we should look in the annals of real crime for confirmation of the truth to life of stories such as these, told in fiction or drama.
The strongest influence, under which the naturally non-criminal person may be tempted in violation of instinct and better nature to the commission of a crime, is that of love or passion. Examples of this kind are frequent in the annals of crime. There is none more striking than that of the Widow Gras and Natalis Gaudry. Here a man, brave, honest, of hitherto irreproachable character, is tempted by a woman to commit the most cruel and infamous of crimes. At first he repels the suggestion; at last, when his senses have been excited, his passion inflamed by the cunning of the woman, as the jealous passion of Othello is played on and excited by Iago, the patriotism of Brutus artfully exploited by Cassius, he yields to the repeated solicitation and does a deed in every way repugnant to his normal character. Nothing seems so blinding in its effect on the moral sense as passion. It obscures all sense of humour, proportion, congruity; the murder of the man or woman who stands in the way of its full enjoyment becomes an act of inverted justice to the perpetrators; they reconcile themselves to it by the most perverse reasoning until they come to regard it as an act, in which they may justifiably invoke the help of God; eroticism and religion are often jumbled up together in this strange medley of conflicting emotions.
A woman, urging her lover to the murder of her husband, writes of the roses that are to deck the path of the lovers as soon as the crime is accomplished; she sends him flowers and in the same letter asks if he has got the necessary cartridges. Her husband has been ill; she hopes that it is God helping them to the desired end; she burns a candle on the altar of a saint for the success of their murderous plan.4 A jealous husband setting out to kill his wife carries in his pockets, beside a knife and a service revolver, a rosary, a medal of the Virgin and a holy image.5 Marie Boyer in the blindness of her passion and jealousy believes God to be helping her to get rid of her mother.
A lover persuades the wife to get rid of her husband. For a whole year he instils the poison into her soul until she can struggle no longer against the obsession; he offers to do the deed, but she writes that she would rather suffer all the risks and consequences herself. "How many times," she writes, "have I wished to go away, leave home, but it meant leaving my children, losing them for ever.. that made my lover jealous, he believed that I could not bring myself to leave my husband. But if my husband were out of the way then I would keep my children, and my lover would see in my crime a striking proof of my devotion." A curious farrago of slavish passion, motherly love and murder.6
There are some women such as Marie Boyer and Gabrielle Fenayrou, who may be described as passively criminal, chameleon-like, taking colour from their surroundings. By the force of a man's influence they commit a dreadful crime, in the one instance it is matricide, in the other the murder of a former lover, but neither of the women is profoundly vicious or criminal in her instincts. In prison they become exemplary, their crime a thing of the past.
Gabrielle Fenayrou during her imprisonment, having won the confidence of the religious sisters in charge of the convicts, is appointed head of one of the workshops. Marie Boyer is so contrite, exemplary in her behaviour that she is released after fifteen years' imprisonment. In some ways, perhaps, these malleable types of women, "soft paste" as one authority has described them, "effacees" in the words of another, are the most dangerous material of all for the commission of crime, their obedience is so complete, so cold and relentless.
There are cases into which no element of passion enters, in which one will stronger than the other can so influence, so dominate the weaker as to persuade the individual against his or her better inclination to an act of crime, just as in the relations of ordinary life we see a man or woman led and controlled for good or ill by one stronger than themselves. There is no more extraordinary instance of this than the case of Catherine Hayes, immortalised by Thackeray, which occurred as long ago as the year 1726. This singular woman by her artful insinuations, by representing her husband as an atheist and a murderer, persuaded a young man of the name of Wood, of hitherto exemplary character, to assist her in murdering
