She thought of what Mitchell had said two days before; that remark about how dangerous her life would become if he weren't there to protect her. It wasn't an empty threat; it had carried weight. She was forfeitable, just like Margie.

"Get a grip," she murmured to herself. This was neither the place nor time to contemplate her vulnerability.

She had to do what she'd come here to do and then get out. Daring the pale face of the clock (which had not worked, Margie had once told her, since the last years of the Civil War) she climbed the rest of the stairs to the second floor. Margie's private sitting room was on this floor; so was her bedroom, and the bathroom where she'd died. Rachel had intended not to go into the bathroom unless she ran out of places to search, but now, marooned on the landing, she knew the proximity of the place would haunt her unless she confronted it. Flipping on the landing light she went to the bedroom door. It was open a few inches. The room was bright: the investigating officers had left all the drapes wide. They'd also left the room in a state of complete disarray; the whole place had clearly been picked over for evidence. This was the only room in the house hung with pictures that reflected Margie's eclectic taste: a cloyingly sweet Chagall, a small Pissarro depicting a little French village, two Kandinskys. And in bizarre contrast to all this color, two Motherwell Elegies, stark black forms against dirty white, which hung like memento mori to either side of her bed.

Rachel picked her way through the numerous drawers which had been pulled out and laid on the floor to be searched, and went to the bathroom door. Her heart began to hammer again as she reached for the handle. She disregarded its din, and opened the door.

It was a big room, all pink marble and gold; the tub-which Margie had loved to lounge in-enormous. "I feel like a million-dollar hooker when I'm in that tub," Margie had liked to boast.

There were still countless reminders of her presence littered about. Perfume bottles and ashtrays, a photograph of her brother Sam tucked into the frame of the Venetian mirror, another photograph (this one of Margie in lacy underwear, taken by a society photographer who'd specialized in aesthetically sleazy portraits), hanging beside the door to the shower. Again, there was also ample evidence that the police had been here. In several places the black marble surface had been dusted for fingerprints, and a layer of dust remained. The congealed remains of a pizza-presumably consumed while the investigators were at work-sat in a greasy box beside the bath. And the contents of the drawers had been sorted through; a selection of questionable items set on the counter. A plethora of pill bottles; a small square mirror, along with a razor (kept for sentiment's sake, presumably; Margie had stopped using recreational cocaine years ago) and a collection of sexual items: a small pink vibrator, a jar of cherry-flavored body lubricant, some condoms.

The sight of all this distressed Rachel. She couldn't help but imagine the officers smirking as they dug through the drawers; making tasteless jokes at Margie's expense. Not that she would have given a damn.

Rachel had seen enough. She wasn't going to be haunted by this place; any power it might have had over her had been trampled away. At least so she thought until she went to switch off the light. There on the wall was a dark spatter. She told herself to look away, but her eye went no further than the next dried drop, which was larger. She touched it. The drop came away on her fingertip, like cracked paint. It was Margie's blood. And there was more of it, a lot more of it, invisible on the speckled marble until now.

Suddenly it didn't matter that the police had defiled the room with their pizza and their sticky fingers. Margie had died here. Oh, God in Heaven, Margie had died here. This was her lifeblood, spilled on the wall: a smear close to Rachel's shoulder, where she'd fallen back or reached out in the hope of keeping herself from falling, a larger dot on the floor between Rachel's feet, almost as dark as the marble.

She looked away, revolted, but the defenses she'd put up to keep herself from picturing what had happened here had collapsed. Suddenly she had the scene before her, in horrid detail. The sound of the shots echoing off the marble, off the mirrors; the look of disbelief on Margie's face as she retreated from her husband; the blood running out between her fingers, slapping on the floor.

What had Garrison done when the shots were fired? Dropped the gun and fallen to his knees beside her? Or stumbled to the phone to call for an ambulance? More likely he'd called Mitchell, or a lawyer; put off the moment when help could come for as long as possible, to be certain that the life had gone from Margie. Every last breath.

Rachel covered her face with her hands, but the image refused to be banished so easily. It pulsed before her: Margie's face, openmouthed; her hands, fluttering, her body, robbed of motion, or the prospect of motion, darkening as the blood spread over it.

"Stop this," Rachel said to herself.

She wanted to get out of the bathroom without looking at it again, but she knew that was the worst thing she could do. She had to uncover her eyes and confront what she'd seen. There was nothing here that could hurt her, except for her own superstition.

She reluctantly let her hands drop from her face and forced herself to study the scene afresh. First the sink and its surrounds; then the mirror and the tub. Finally, the blood on the floor. Only when she'd taken it all in did she turn to leave the bathroom.

Where now? The bedroom lay before her, with all the drawers laid out. She could waste an hour going through the room, but it was a fool's errand. If the letters were here, then they were so well hidden the police had failed to find them, and so, more than likely, would she.

Instead she picked her way back across the littered floor to the landing and crossed to Margie's sitting room. She glanced at her watch as she did so. She'd been in the house twelve minutes already. There was no time for further delay.

She opened the sitting room door, and immediately retreated, pursued out onto the landing by Didi, Margie's pug, who yapped with all the ferocity of a dog three times his size.

"Hush, hush-." She dropped down to her knees so he could sniff her hands. "It's only me."

He ceased his din on the instant, and instead began a round of grateful mewlings, dancing around in circles before her. She'd never much cared for the animal, but her heart went out to it now. It was doubtless wondering where its mistress had disappeared to, and took Rachel's presence as a sign of her return.

"You come with me," she said to the animal. It duly trotted after her into the sitting room, where a plate of uneaten food and an excrement-caked newspaper testified to its sorry state. The rest of the room was in a far tidier condition than either the bedroom or the bathroom. Either the police had neglected to examine it thoroughly, or else the officer who'd done so was a woman.

Rachel didn't linger. She immediately started to go round the room, opening every cupboard and drawer. There were plenty of plausible hiding places-rows of books (mostly airport romances), heaps of Broadway playbills, even a collection of letters (all of them from charitable organizations begging Margie's support)-but there was no sign of anything vaguely incriminating. Didi stayed close by throughout the search, plainly determined not to lose his companion now he had her. Once only did he leave her side, waddling to the door as though he'd heard somebody in the house. Rachel paused and ventured out onto the landing, listening as intently as the dog, but it seemed to be a false alarm. Back to her search she went, checking on the time as she did so. She'd spent almost half an hour in the sitting room; she couldn't afford to stay in the house much longer. But if she left empty-handed, would she have the courage to return? Certainly she'd used up every cent of enthusiasm she had for the venture. It wouldn't be easy to persuade herself to repeat the process; not now that she had specifics to dwell on: the blood, the murk, the disarray.
