"You understand what happened had to happen. It couldn't have turned out any other way. A woman's depressed - with herself, with life. With her husband, who had made life possible for her, until he was bewitched by another woman. A destroyer. Abandoned. Like someone left for dead. She plans her suicide, until the dream begins. In the dream, the destroyer is destroyed. That's a dream worth living for. Now, with such simplicity, such clarity, everything falls into place. It must be a crime that her husband can declare unsolved and be believed by all the world. She must make it look like a rape, but she must leave her husband the clues. Once he discovers who it was, he'll put the case into the file of unsolved murders. Another break-in by some sex-crazed man. But all his life, he'll know that it was her. She remembers a set of glasses she bought for the woman some time before - a housewarming gift from her husband and his office. She buys another set. Her husband has a beer one night - doesn't even comment on the glass. Now she has his fingerprints. Then on a few mornings, she saves the fluid that comes out when she removes her diaphragm. Puts it in a plastic bag. Puts the bag in the basement freezer, and waits. She calls the woman and asks to see her. Stops first at the U and logs into the computer. Now she has her alibi."
