She did not masturbate.

Zoe opened the tub drain and stood cautiously. She turned on the shower and rinsed the suds away. She sniffed at her armpits, but smelled only the flowery fragrance of the imported soap. She dried thoroughly and inspected herself for more gray pubic hairs, but found none.

She returned to the bedroom. She turned on the bedside radio, switching from WQXR to a station that featured hard rock. Sitting on the edge of the bed, listening to the driving music, she painted her toenails and fingernails a glossy vermilion. Then she walked about the room, waving her hands in the air to dry the polish and moving her body in time to the music.

Taking care not to smudge her nails, she opened the bottom drawer of her dresser and lifted out stacks of sensible underwear and earth-colored pantyhose. In the back of the drawer were concealed her treasures. Her precious things.

She selected a brief brassiere and a bikini of sheer black nylon with small appliqued leaves that concealed the nipples and pudendum. The lingerie came on with a whisper, weightless and clinging. She applied Aphrodisia behind her ears, within her armpits, on the inside of her thighs.

In the back of the bedroom closet, behind the rack of practical, everyday clothes, were her secret costumes. They hung in plastic bags from hooks screwed into the wall. There were five gowns, all expensive, all new. The red silk had been worn once. The others had never been used.

She donned a sheath of black crepe. When the side zipper was closed, the dress clung like paint. A second skin. Decolletage revealed the swell of her hardened breasts. Her slender waist was accented, the lyre of her hips. In back, firm buttocks pressed.

Then, seamed black silk hose with rosetted garters. Evening sandals of thin straps with three-inch spike heels, the tallest she could manage. She wore no jewels, but around her left wrist she; fastened a fine chain supporting a legend of gold letters. It read:

She combed her short brown hair quickly. Then went into the living room, to the closet. In the back, concealed, was her trenchcoat and a large patent leather shoulder bag. In the bag, wrapped in tissue, was a black nylon wig and a makeup kit.

She spent a few moments transferring things from her workaday bag: cigarettes, matches, Swiss Army pocket knife, the small can of Chemical Mace, keys, coins, wallet with slightly more than forty dollars. Before she transferred the wallet, she removed all her identification cards and hid them on the top shelf of the closet.

Then she shrugged into the trenchcoat and buttoned it up to her neck. She buckled the belt loosely so the coat hung like a sack. Slinging her shoulder bag, she sallied forth leaving all the lights in the apartment burning.

Bathing and dressing had taken almost an hour. Never once during that time had she looked in a mirror.

The night doorman was behind the desk and tipped his cap to her as she passed. She teetered over to Third Avenue on her high heels. She looked about nervously for Ernest Mittle, but he was long gone.

There were sudden swirls of light, powdery snow, and she had to wait almost five minutes for an uptown cab. She told the driver to take her to Central Park West and 72nd Street.

"The Dakota?" he asked.

"That corner," she said crisply. "It's close enough."

"Whatever you say, lady," he said, and then drove in silence, for which she was thankful.

She gave him a generous tip when he let her off. She stood on the windswept corner, lighting a cigarette slowly and not moving in any direction until the cab pulled away, and she saw its taillights receding west on 72nd Street.

Then she, too, headed west, walking rapidly, her heels clicking on a sidewalk already dusted with snow. Men passed, but she did not raise her eyes. She bent against the wind, clutching her shoulder bag with both hands. But she was not cold. She glowed.

The Filmore was a residential hotel. Downstairs, one flight from the sidewalk, was a dim restaurant featuring a "continental menu." The restaurant seemed to be languishing, but the connecting bar, brightly lighted, had several customers, most of them watching a TV set suspended on chains from the ceiling.

Zoe Kohler had been there once before. It suited her needs perfectly.

She sat at the bar in her trenchcoat, holding her bag on her lap. She ordered a glass of white wine and finished it quickly. Very calm. Making certain she looked at none of the single men. The bartender was not the one who had been on duty during her previous visit.

"Where is the ladies' room, please?" she asked, just as she had before.

"Back there through the hotel entrance," he said, pointing. "You go up the stairs and through the lobby. It's to your right."

"Thank you," she said, paid for her wine and left a tip. Not too large a tip, she judged, and not too small. He'd never remember her. No one ever did.

The lavatory was tiled in white with stained fixtures of cracked porcelain. Disinfectant stung the nose. There was a middle-aged woman at one of the sinks, inspecting herself in the streaked mirror, moving her head this way and that. She turned when Zoe came in.

"Hullo, dearie," she said brightly, smiling.

Zoe nodded and walked down the row of five toilet stalls, glancing under the doors. They all appeared to be unoccupied. She went into the last stall, closed the door and latched it. She waited patiently for two or three minutes, then heard the outside door open and close.

She exited cautiously. The restroom seemed to be empty, but to make certain, she opened the doors of all the stalls and checked. Then she went over to one of the sinks and began working swiftly. Finally, finally, she looked at her image.

She removed the wig from her shoulder bag, shook it out, pulled it on. The nylon was black and glossy, with feathered curls across her brow and thick, rippling waves that fell almost to her shoulders. She smoothed it into place, turning this way and that, just as the middle-aged woman had.

Satisfied, she began applying makeup. She darkened her brows, mascaraed her lashes, brushed on silvery-blue eye shadow, powder, rouge, a deep crimson lipstick with an outer layer of moist gloss.

She worked quickly, and within fifteen minutes the transformation was complete. Even in the dulled mirror she looked vibrant, alive. She was a warm, sensuous woman, eager for joy. Glittering eyes challenged and promised.

She opened her coat to snug the wool crepe dress down over her hips, wiggling slightly to make certain it fit without a wrinkle. She tugged the neckline lower, took a deep breath and, in the mirror, showed her teeth.

Then she wrapped the unbuttoned trenchcoat about her, cinched the belt tight, and turned up the collar in back. Her neck and the top of her bosom were exposed.

She examined herself. She licked her lips.

She exited through the hotel lobby, bag swinging from her shoulder. Men in the lobby stared at her. Men passing on the sidewalk outside stared at her. She lighted a cigarette, smoking with outsize, theatrical movements.

She waited under the marquee for a cab, humming.

The Hotel Pierce, Manhattan's newest hostelry, occupied the entire blockfront on Sixth Avenue between 56th and 57th streets. It had 1200 rooms, suites, penthouses, banquet rooms, meeting rooms, a convention hall, a nightclub on the roof.

Below the main lobby floor was a concourse with three dining rooms, a coffee and snack bar, gift shops and boutiques, the offices of travel agents and a stockbroker, a bookstore, men's and women's clothing shops, and four cocktail lounges. "You can live your life at the Pierce" was the advertised boast.

Zoe Kohler had selected the Pierce because she knew it was currently hosting three conventions; the concourse cocktail lounges were sure to be crowded. She chose the El Khatar, a bar with a vaguely Moorish theme, walls hung with silken draperies, waitresses dressed as belly dancers.
