Edna’s husband is unfaithful to her and has been accustomed to going out with the other woman. She is about to become a mother and broods over her loneliness. She finds a woman’s card in her husband’s pocket and becomes suspicious. She watches his office, sees a woman enter, and follows her in. The husband is caught in a compromising position with the woman, so the wife demands a large sum of money to spend on the expected child. Twenty-five years later the son is known as the Vampire because of his hatred of women. Born while his mother was embittered by her experience, his hatred for women is almost uncanny. The Vampire attends a house party, and is shunned by the men but much sought after by the women. It is strange that though he hates women they invariably seek him out. One of the married women at the party takes a violent fancy for Mr. Vampire, which causes comment. The maid at the house has taken a liking to the strange Vampire, who, on several occasions has spoken kindly to her. Mrs. Brooks, the married woman in the case, goes to his room, intending to leave a note for him. The maid is in a room nearby and hears her enter. Brooks has suspected that his wife is pursuing the Vampire, and, securing a revolver, follows her. The Vampire man comes into his room, finds the note and reads it. The wife, meanwhile, has not had a chance to get out and hides behind some curtains. The maid, too, comes in and hides. Brooks forces his way into the room and threatens to kill the Vampire Man, telling him that he knows that Mrs. Brooks is hidden there. He is about to shoot, when the maid comes from behind the curtains. Brooks thinks that he is mistaken and apologizes. The wife realizes her wrongdoing, and, after her husband’s departure, sneaks out, unseen. The Vampire Man sardonically smiles at the ways of women and reiterates his hatred for them.
