‘You want me to put my name behind it, you mean? You’ve got a nerve, Rocco.’ Massin sounded annoyed, but there was no way he could refuse the request without having a solid reason.

Rocco pressed ahead before Massin could find one. ‘If someone is trying to kill this man, it could be something to do with his wartime activities. I’d rather stop it before he tries again and ends up killing a bunch of innocent villagers. Plastic explosive is hardly selective in its victims.’

The potential headlines were evidently clear enough for Massin to imagine. Equally clear to him would be the dangers of digging into events which few people wanted to uncover. ‘All right,’ he said reluctantly. ‘Leave it with me. What about the other thing?’ He meant Paris and the Berbiers.

‘I’m making enquiries. There’s somebody local who might know what happened. I just have to winkle them out of the woodwork.’ It was as near a lie as Rocco had ever uttered. He didn’t know if anybody in Poissons was involved, but the suggestion might be enough to keep Massin off his back.

He rang Claude. The garde champêtre sounded groggy. Rocco guessed he’d been taking a nap.

‘How many suspicious deaths have there been in this area recently?’ he asked.

‘Suspicious? You mean murders? That’s easy: none. Why?’

‘And assaults? By that I mean anything beyond a bad-tempered punch-up?’

‘Same answer. It hasn’t happened. Sorry to disappoint you, Lucas, but life out here isn’t like Paris. People argue, sure – even have lifelong feuds. But that’s all it is. The last sudden death we had was last year, but that was a hunting accident. A visitor got careless in the woods and ran into a charge of buckshot. It happens, unfortunately; and for the fascists in the anti-gun lobby, far too often.’

Rocco was aware of the hunting and shooting argument: that many legal guns found their way into the hands of criminal elements, quite apart from the deaths caused in communities by accident or intent. ‘You don’t approve?’

‘No. I mean, there are idiots out there with guns, we know that. But if the bureaucrats got their way, they’d shut it down altogether. Christ, it’s un-French!’

Rocco laughed. ‘Did anyone pursue the matter?’

‘No. There was a witness standing right next to the man who was killed. He didn’t see the shooter, but he said there was a big group of outsiders in the woods on a hunting weekend and it could have been any one of them. Whoever pulled the trigger probably didn’t even know what he’d done. The Amiens office declared it an accidental death due to not knowing the local terrain.’

Rocco sighed. It looked as if Poissons-les-Marais possessed an almost surreal lack of crime, and the only occurrence which had come close was an accident. But that made recent events even more out of the ordinary. ‘OK. Just working a line of thought, that’s all.’ He was about to put down the phone when a random thought occurred to him. ‘Who was the witness to that shooting?’

Claude gave a dry chuckle. ‘Funny you should ask. It was Didier Marthe.’

Rocco was jerked awake two hours later by the phone. He shook his head and checked the time. Six o’clock. He was beginning to regret having the damned thing installed.

‘Rocco?’ A vaguely familiar voice came over the line. ‘Is that you?’

‘Speaking.’ He swung his feet onto the floor. ‘Who is this?’

‘Bernard Rizzotti – Amiens préfecture. You came to see me about the dead woman.’

‘So I did. What have you got?’

‘The results came in.’ Rizzotti sounded subdued. ‘It’s maybe not what you were hoping for, though.’

‘Go on.’ Rocco experienced a sinking feeling. This wasn’t going to be good.

‘She was clean. Alcohol, yes – a fair amount, in fact. But no drugs.’

Rocco swore quietly. So, a simple accident: a young woman who’d had too much to drink went walking near water and fell in. It happened.

But Rizzotti hadn’t finished speaking. ‘There’s something else. The deceased was pregnant.’

‘You’re sure?’ Rocco flicked through the possibilities, wondering how that might tie in with Nathalie Berbier’s death. Depression at finding herself pregnant leading to excess drinking and a fatal stumble in the dark? An angry lover – perhaps married – furious at hearing the news and pushing her into a river to silence her? Or the lonely realisation that she had made a dreadful mistake … and seeing only one way out?

‘I’m certain. Without the body I can’t tell how far gone she may have been, but I can tell you it wasn’t physically obvious when I made my initial examination.’

‘I understand. So why tell me now?’

‘Well, because it changes things … her being pregnant.’

‘I see.’ It sounded like Rizzotti had a soft side. Rocco sensed that he wanted to say more, but was hesitant. ‘If there’s anything else, it goes no further.’

A long pause, then Rizzotti said quietly, ‘This is not to be broadcast, you understand. I will deny all knowledge if you use my name in connection with this.’

‘Go on.’

‘When I first examined the stomach contents, there was some alcohol. But it was difficult to judge how much because it was mixed with a large quantity of clean water, as were the lungs.’

Proof of drowning at least. Then Rocco stopped. ‘Clean water? Not lake water?’

‘Clean-ish, I’d say. Either from a fast-running stream where there’s little or no pollution or silt … or near a source of natural water … say a spring.’

Fresh water. As good as Evian. He recalled Claude’s words. The Blue Pool.

Rizzotti was still speaking. ‘But to have fallen into water and been unable to get out would indicate a severe level of intoxication or the presence of a powerful narcotic, such as cannabis or heroin … maybe even one of the new synthetic drugs being manufactured in America. That would severely reduce a person’s ability to function normally – especially a young woman.’

‘So what’s the problem?’

‘The lab figures do not bear that out. They simply state the presence of a powerful sedative and the conclusion that the deceased consumed too many tablets in error, perhaps while intoxicated, and fell to her death in a stretch of water.’

Rocco felt the air hum around him. ‘But you don’t agree.’

‘Most assuredly not.’ Rizzotti sounded almost angry yet resolute. ‘Her system showed signs of an excessive dose of barbiturates, that is undeniable. But to have reached the level stated would have required the digestion of a great many pills indeed. Yet I did not find any such residue in her stomach.’

‘Which means?’ Rocco sat up.

‘The reported figures are mistaken … or ill-founded.’

‘You mean they’ve been altered.’

‘I can’t say that for sure.’ Rizzotti was careful to avoid levelling any direct accusation towards the forensic laboratory.

Rocco didn’t push it. He might need the doctor’s help later. Alienating him by backing him into a corner wouldn’t ensure that, not now he’d come out this far.

‘What’s your conclusion, Doctor?’

‘There is only one. If it wasn’t in her stomach – ingested normally, in other words – there is only one explanation for such a high dose of barbiturates: she must have been injected with it before she died.’

A few seconds went by as if Rizzotti was aiming at the maximum effect. ‘This was no drunken accident, Inspector Rocco. I think that poor woman was murdered.’

CHAPTER TWENTY-THREE

‘Tell me about this.’ Rocco dropped the photo of the Resistance group on Didier’s hospital bed the following morning. The scrap man had been placed in a single room with a view over some gardens, a facility Rocco thought was better treatment than he deserved.

‘Never seen it before,’ Didier Marthe muttered sourly. The response was too quick to be anything but instinctive, but he was staring at the print as if it might bite him. ‘Where did you get it?’
