Reynolds put his back to the kitchen door, and tried to edge his way upright, using the door-handle as purchase. But his head was spinning: a carousel of horrors, round and round, each horse uglier than the last. His legs doubled up under him, and he fell down like the senile fool he was. Damn. Damn. Damn.

Gavin heard Reynolds fall, but he was too busy arming himself to hurry back into the kitchen. If the intruder who'd attacked

Reynolds was still in the flat, he wanted to be ready to defend himself. He rummaged through the reports on the desk in the study and alighted on a paper knife which was lying beside a pile of unopened correspondence. Thanking God for it, he snatched it up. It was light, and the blade was thin and brittle, but properly placed it could surely kill.

Happier now, he went back into the hall and took a moment to work out his tactics. The first thing was to locate the bathroom, hopefully there he'd find a bandage for Reynolds. Even a clean towel would help. Maybe then he could get some sense out of the guy, even coax him into an explanation.

Beyond the kitchen the hallway made a sharp left. Gavin turned the corner, and dead ahead the door was ajar. A light burned inside: water shone on tiles. The bathroom.

Clamping his left hand over the right hand that held the knife, Gavin approached the door. The muscles of his arms had become rigid with fear: would that improve his strike if it was required? he wondered. He felt inept, graceless, slightly stupid.

There was blood on the door-jamb, a palm-print that was clearly Reynolds'. This was where it had happened - Reynolds had thrown out a hand to support himself as he reeled back from his assailant. If the attacker was still in the flat, he must be here. There was nowhere else for him to hide.

Later, if there was a later, he'd probably analyse this situation and call himself a fool for kicking the door open, for encouraging this confrontation. But even as he contemplated the idiocy of the action he was performing it, and the door was swinging open across tiles strewn with water-blood puddles, and any moment there'd be a figure there, hook-handed, screaming defiance. No. Not at all. The assailant wasn't here; and if he wasn't here, he wasn't in the flat.

Gavin exhaled, long and slow. The knife sagged in his hand, denied its pricking. Now, despite the sweat, the terror, he was disappointed. Life had let him down, again - snuck his destiny out of the back door and left him with a mop in his hand not a medal. All he could do was play nurse to the old man and go on his way.

The bathroom was decorated in shades of lime; the blood and tiles clashed. The translucent shower curtain, sporting stylised fish and seaweed, was partially drawn. It looked like the scene of a movie murder: not quite real. Blood too bright: light too flat.

Gavin dropped the knife in the sink, and opened the mirrored cabinet. It was well-stocked with mouth-washes, vitamin supplements, and abandoned toothpaste tubes, but the only medication was a tin of Elastoplasts. As he closed the cabinet door he met his own features in the mirror, a drained face. He turned on the cold tap full, and lowered his head to the sink; a splash of water would clear away the vodka and put some colour in his cheeks.

As he cupped the water to his face, something made a noise behind him. He stood up, his heart knocking against his ribs, and turned off the tap. Water dripped off his chin and his eyelashes, and gurgled down the waste pipe.

The knife was still in the sink, a hand's-length away. The sound was coming from the bath, from in the bath, the inoffensive slosh of water.

Alarm had triggered flows of adrenalin, and his senses distilled the air with new precision. The sharp scent of lemon soap, the brilliance of the turquoise angel-fish flitting through lavender kelp on the shower curtain, the cold droplets on his face, the warmth behind his eyes: all sudden experiences, details his mind had passed over 'til now, too lazy to see and smell and feel to the limits of its reach.

You're living in the real world, his head said (it was a revelation), and if you're not very careful you're going to die there.

Why hadn't he looked in the bath? Asshole. Why not the bath?

'Who's there?' he asked, hoping against hope that Reynolds had an otter that was taking a quiet swim. Ridiculous hope. There was blood here, for Christ's sake.

He turned from the mirror as the lapping subsided - do it! do it! - and slid back the shower curtain on its plastic hooks. In his haste to unveil the mystery he'd left the knife in the sink. Too late now: the turquoise angels concertinaed, and he was looking down into the water.

It was deep, coming up to within an inch or two of the top of the bath, and murky. A brown scum spiralled on the surface, and the smell off it was faintly animal, like the wet fur of a dog. Nothing broke the surface of the water.

Gavin peered in, trying to work out the form at the bottom, his reflection floating amid the scum. He bent closer, unable to puzzle out the relation of shapes in the silt, until he recognised the crudely-formed fingers of a hand and he realised he was looking at a human form curled up into itself like a foetus, lying absolutely still in the filthy water.

He passed his hand over the surface to clear away the muck, his reflection shattered, and the occupant of the bath came clear. It was a statue, carved in the shape of a sleeping figure, only its head, instead of being tucked up tight, was cranked round to stare up out of the blur of sediment towards the surface. Its eyes were painted open, two crude blobs on a roughly carved face; its mouth was a slash, its ears ridiculous handles on its bald head. It was naked: its anatomy no better realised than its features: the work of an apprentice sculptor. In places the paint had been corrupted, perhaps by the soaking, and was lifting off the torso in grey, globular strands. Underneath, a core of dark wood was uncovered.

There was nothing to be frightened of here. An objet d’art in a bath, immersed in water to remove a crass paint-job. The lapping he'd heard behind him had been some bubbles rising from the thing, caused by a chemical reaction. There: the fright was explained. Nothing to panic over. Keep beating my heart, as the barman at the Ambassador used to say when a new beauty appeared on the scene.

Gavin smiled at the irony; this was no Adonis.

'Forget you ever saw it.'

Reynolds was at the door. The bleeding had stopped, staunched by an unsavoury rag of a handkerchief pressed to the side of his face. The light of the tiles made his skin bilious: his pallor would have shamed a corpse.

'Are you all right? You don't look it.'

I’ll be fine ... just go, please.'

'What happened?'

'I slipped. Water on the floor. I slipped, that's all.'

'But the noise ...'

Gavin was looking back into the bath. Something about the statue fascinated him. Maybe its nakedness, and that second strip it was slowly performing underwater: the ultimate strip: off with the skin.

'Neighbours, that's all.'

'What is this?' Gavin asked, still looking at the unfetching doll-face in the water.

'It's nothing to do with you.'

'Why's it all curled up hike that? Is he dying?'

Gavin looked back to Reynolds to see the response to that question, the sourest of smiles, fading.

'You'll want money.'

'No.'

'Damn you! You're in business aren't you? There's notes beside the bed; take whatever you feel you deserve for your wasted time - ' He was appraising Gavin.' - and your silence.'

Again the statue: Gavin couldn't keep his eyes off it, in all its crudity. His own face, puzzled, floated on the skin of the water, shaming the hand of the artist with its proportions.

'Don't wonder,' said Reynolds.
