He kicked out, sending a fragile coffee table spinning across the room, smashing an ornate mirror from Florence. They were nothing, merely trappings; he could buy a dozen, a hundred more like them if he chose.

She had betrayed him. It was all he could see, all he could think about. Betrayed and made a fool of him in the eyes of the world. But she also knew too much, his whore of a wife. And in betraying him, she had brought about her own destruction.

He picked up the telephone to call first his brother Lakhdar, in Paris, then Bouhassa. Because of her betrayal he was going to have to bring forward his plans. It was earlier than he would have liked, but maybe this was a sign from the gods.

How did that saying go? Faire d’une pierre deux coups. Yes, he liked that. It was strangely appropriate.

Kill two birds with one stone.

CHAPTER EIGHT

Rocco recognised the smell the moment he stepped from his car. It was one he’d encountered all too often whenever a ‘floater’ – often a misnomer but darkly descriptive – surfaced after a period underwater.

He walked down a narrow footpath, where he found Claude Lamotte in conversation with two men in work clothes, breathing vapour and slapping gloved hands against the cold rolling off the canal. The call to Amiens had come from a café in the next village, where Claude, huddled in rubber boots and a heavy hunting jacket and wearing a cap with ear flaps jammed down over his head, had sent a messenger. His uniform shirt was just visible at the lapels, proving that he had, at least, made an effort to meet official dress requirements.

‘What have we got?’ asked Rocco.

Claude pointed into the murky water at the barge’s stern, to where a bundle of dark-green cloth was visible just below the waterline. Further down was the outline of a bare foot, the skin dark and shrivelled. ‘The boatman said he felt it being dragged by something in the water. He thought it might be a submerged log or a dead cow.’ He met Rocco’s sceptical look with a shrug. ‘It happens, believe me. Cows are good at getting into the canal but not so clever at climbing out again. After a while they give up and drown.’ As a rural policeman, part of Lamotte’s job was monitoring the canal and other waterways in the area, which meant taking calls involving accidental deaths by drowning.

‘Hell of a surprise for him, then.’

‘He hooked the cloth and gave it a tug, but it was stuck. The clothing must have snagged on a loose rivet. The body surfaced briefly before going under again. Says he got a good look at it before it got dragged under again. It gave him a turn so he left it alone and called me. He’s had a few drinks since then, so I wouldn’t stand too close – and don’t light a cigarette; he’ll go up like a Roman candle.’

Rocco nodded. The boatman was short, grubby and grizzled, with a tangle of grey beard and a head topped by a battered peaked cap. ‘I’ll pass, in that case. But I need to know where he’s come from and where he thinks he might have picked it up.’

‘Easy.’ Claude pointed along the canal, which ran straight for several hundred metres before bending away out of sight behind a line of poplar trees. ‘He set out from two kilometres away early this morning, this side of Poissons. It’s all straight from there, with no locks for a long way,’ he gestured behind them with his thumb, ‘and he reckons it was about half a kilometre back when he felt the barge’s nose coming round, like she’d grounded. Is a barge a ‘she’ or a ‘he’, d’you think?’

‘If she won’t do what you want,’ Rocco countered dryly, ‘what do you reckon?’ He studied the vessel, which was about fifteen metres long and sitting low in the water like a giant slug. It looked a brute of a workhorse, battered and scarred and weighed down with sacks of coal, and not the least bit feminine. ‘Would he have noticed it in a thing this size?’

‘Sure.’ Claude nodded. ‘Apparently they can tell by feel when a barge isn’t running right. He said it was pulling to one side.’

Rocco took his word for it. His own experience with boats had been confined to jumping in and out of assault craft. He looked along the canal in the direction the barge was facing. It wasn’t an area he was yet familiar with. ‘Where does this lead?’

‘It’s part of the River Somme. It goes through Amiens and up to Abbeville.’

‘OK. Let’s get the body out of there. We can’t tell what happened until we see it properly. Make sure you hook the clothing.’

Claude asked the boatman to get his boathook. But after much arguing, it was obvious the man was too unsteady on his feet to be of any help. Claude jumped on board and found the tool himself, then began tugging at the submerged body. After a few minutes, he managed to work the clothing free and carefully manoeuvre the corpse clear of whatever was holding it in to the bank. Rocco enlisted the help of the two bystanders to haul it dripping onto the towpath.

‘It’s been there a while,’ Rocco commented. The smell was immediate and rancid, driving the other men back more effectively than any police barrier might have done. Rocco, however, had seen it all before and was almost immune. Even so, he had to take a deep breath before making an examination. The body was bloated, straining against the clothing like an overstuffed andouille, the skin covered with a slimy film. He pulled a pair of orange rubber gloves from his pocket and slipped them on, a habit picked up from a member of the river police in Paris. Then he checked the pockets. He found a wallet in the jacket, empty save for a photo discoloured beyond recognition and a square of pulpy paper with faint traces of ink. It might have given a clue to the man’s origins, but fell apart as soon as he touched it.

He turned his attention to the dead man’s face. He estimated his age at somewhere between thirty and forty years, but it was difficult to be sure, given the conditions. Even with the swollen, discoloured skin, he looked swarthy, with thick, rough-cut hair. Definitely of North African or maybe Spanish origin, though. He flipped the jacket open, but there were no labels to indicate where it might have been bought.

It reminded him of another body that had been discovered near Poissons on his first day in the region. Then, it had been a young woman in the military cemetery outside Poissons, and equally difficult to age or identify.

‘He’s not local,’ said Claude emphatically.

‘You know that for sure?’

Claude pointed at the man’s other foot, which was encased in a heavy leather sandal with a thick sole. ‘It’s too cold here for that footwear. It’s the sort of thing you see in the flea markets down south. Or in North Africa.’

Rocco looked at him. He’d never thought of Claude having served overseas. On the other hand, conscription into the French army took men to strange places.

‘I did a tour there once,’ Claude explained. ‘Can’t say I was impressed.’ He flapped a hand in front of his face and cleared his throat. ‘What do we do with him? He’ll only get worse out here.’

‘Get a wagon out from Amiens. We’ll let Rizzotti take a look. I’ll follow it in.’ Rocco pulled off the gloves and dropped them by the body. He had a spare pair in the car.

‘And Capitaine Haddock?’ Claude nodded in the direction of the barge owner, who seemed to be sinking slowly into a gentle stupor and becoming detached from everything around him, even the cold.

‘Pour a couple of litres of coffee down his throat and take a statement. Then let him go.’

‘Shouldn’t we keep him around?’

‘He’s not going far in that thing, is he? And I doubt he ran the man down – not at speed, anyway.’

‘Stabbed to death. One thrust to the chest.’ Dr Rizzotti stepped back from the body on his examining table and coughed discreetly. In spite of the tang of chemicals in the room, even the doctor was looking slightly green around the eyes. ‘Dead when he went in, probably been that way for three to four days. The water in the canal would be very cold at this time of year, so it might have been longer.’ He shrugged apologetically. ‘It’s a science. But for me, not a precise one, I’m afraid.’
