The doctor wasn’t an expert on the latest forensic techniques of practical homicide investigation, but he was reasonably sure that latent fingerprints on human skin lasted only a few hours or less. They could be lifted with the use of lasers and other sophisticated equipment, but he knew simpler procedures might also be effective. Kromekote cards or unexposed Polaroid film, pressed firmly to the skin, will transfer the incriminating print; when the card or film is dusted with black powder, a mirror image of the latent print appears and must then be reversed through photography. Magnetic powder applied with a Magna Brush directly to the skin is acceptable in a pinch, and the iodine-silver transfer method is an alternative if a fuming gun and silver sheets are close at hand.
He didn’t expect Susan’s body to be found for five or six hours, perhaps much longer. By then, the early stages of decomposition would have eradicated all the latent prints on her skin.
Nevertheless, he had touched virtually every plane and curve of her body — and often. To be a winner at these games, one had to play with energetic enthusiasm but also with a detailed knowledge of the rules and with a talent for strategy.
He suggested that Susan draw a hot bath. Then step by step he walked her through the remaining minutes of her life.
While the tub was filling, she got a safety razor from one of the vanity drawers. She had used it to shave her legs; but now it would serve a more serious purpose.
She twisted open the razor and extracted the single-edge blade. She put the blade on the flat rim of the bathtub.
She undressed for the bath. Naked, she didn’t look broken, and Ahriman wished he could keep her.
Waiting for further instruction, Susan stood beside the bathtub, watching the water gush out of the faucet.
Studying her reflection in the mirror, Ahriman took pride in her tranquility. Intellectually, she was aware that she would soon be dead, but because of the excellent work he’d done with her, she lacked the capacity for genuine and spontaneous emotional response while in this state of total personality submersion.
The doctor regretted that the time inevitably came when each of his acquisitions must be discarded and allowed to go the way of all flesh.
He wished he could preserve each of them in perfect condition and set aside a few rooms of his house to a display of them, just as he currently dedicated space to his Corgi model cars, die-cast banks, playsets, and other enthusiasms. What a delight it would be to walk among them at will, these women and men who had been both his cat’s-paws and his companions over the years. With his own engraving kit, he could lovingly prepare brass plaques featuring their names, vital statistics, and dates of acquisition — just as he did for items in his other collections. His videotapes were splendid mementos, but they were all motion in two dimensions, providing none of the depth or the satisfying tactility that physically preserved playthings could offer.
The problem was rot. The doctor was a perfectionist who would not add an item to one of his collections unless it was in mint or near-mint condition. Not for him the merely excellent or very good example. Because no known form of preservation, from mummification to state-of-the-art embalming, could meet his high standards, he would of necessity continue to rely on his videotapes when overcome by a nostalgic and sentimental mood.
Now, he sent Susan to the dining room to retrieve the notepad on which she had written her farewell to life. She returned with it and placed it on the freshly polished tile top of the vanity, next to the sink, where it would be found simultaneously with her cadaver.
The bath was ready. She turned off both faucets.
She added scented salts to the water.
The doctor was surprised, because he had not instructed her to spice the bath. Evidently, she always did so before stepping into the tub, and this act was essentially a conditioned reflex that required no volitional thinking. Interesting.
Writhing vines of steam, rising from the water, now bloomed with the faint fragrance of roses.
Sitting on the closed lid of the toilet, careful not to touch anything with his hands, Ahriman instructed Susan to enter the bath, to sit, and to bathe herself with special thoroughness. There was no longer any danger that a laser, Kromekote card, Magna Brush, or fuming gun could turn up incriminating fingerprints on her skin. He was counting on the action of her bath to flush out and disperse all of his semen, as well.
No doubt, in the bedroom and elsewhere in the apartment, he had left behind hairs and fibers from his clothing that could be gathered in a police-lab vacuum. Without good fingerprints, however, or other direct evidence that could put him on a list of suspects, they would not be able to trace these scraps of evidence back to him.
