Two hours earlier

During the Nazi occupation of Paris the sprawling honeycomb of austere rooms and dark corridors had been used as a Gestapo prison and interrogation centre. Nowadays the enormous basement beneath the police HQ housed, among other things, the forensic lab and morgue. It was as though the place couldn’t shake off its gruesome heritage.

Luc Simon was standing with the forensic pathologist, the tall thin white-haired Georges Rudel, in a stark neon-lit examination room. On the slab in front of them, a corpse lay covered in a white sheet. Only the feet were visible, protruding from underneath, pallid and cold. A label dangled from one toe. Simon wasn’t a squeamish man but he fought the urge to look away as Rudel casually peeled back the sheet far enough to uncover the corpse’s head, neck and chest.

They’d cleaned Michel up since the last time Simon had seen him, but he still wasn’t a pretty sight. The bullet had entered under the chin, carved its wound channel up behind the face, taking most of it away before exiting through the top of the head. Just one eye remained, sitting in its socket like a hard-boiled egg with a pupil that seemed to stare right at them.

‘What’ve you got for me?’ Simon asked Rudel.

The pathologist pointed at the mess of Michel’s face. ‘Damage here is all consistent with the bullet found in the ceiling,’ he said, speaking mechanically as though dictating a report. ‘Entry wound here. Weapon was held against the upper chest with the muzzle in loose contact with the lower jaw. Edges of the entry wound are burned from combustion gases and blacked with soot. The weapon was a Smith and Wesson revolver, three inch barrel, .44 Remington Magnum. The powerful calibre accounts for the amount of bone and tissue damage.’

Simon tapped his foot impatiently. He hoped that this was leading somewhere.

‘Typically that calibre uses much slower-burning powder than you get with semi-auto rounds like the nine millimetre,’ Rudel went on matter-of-factly ‘That means you get a lot of unburnt residue, especially with a short barrel. Doesn’t burn so clean.’ He pointed. ‘You can see it all here, embedded in the skin. Also here down the neck.’

Simon nodded. ‘OK, so what are you telling me?’

Rudel turned to look at him with bleary eyes. ‘The victim’s prints are on the stocks and the trigger of the weapon. So we know he fired the shot without gloves.’

‘He was found still clutching the gun. No gloves. We know that. Are you going to cut to the chase before one of us dies?’

Rudel ignored the sarcasm. ‘Well, this is what I find perplexing. With all this mess of unburnt powder I’d expect to find a lot of it on the gun hand, as well as the normal chemical discharge that blows back when the weapon is fired. But this man’s hands are clean.’

‘You’re sure about this?’

‘Quite sure–it’s a simple swab test for residue.’ Rudel reached down and lifted a pale lifeless arm out from under the sheet. ‘See for yourself.’

‘You’re saying he didn’t fire the shot.’

Rudel shrugged, and let the dead hand flop back down by the corpse’s side. ‘Only thing on this man’s hands, apart from the usual sweat and grease, are some traces of oily fish. Pilchard, to be precise.’

It struck Simon as absurd, and he laughed. ‘You ran a test for pilchard?’

Rudel looked at him coldly. ‘No, there was a half-opened tin of it on his kitchen table, next to a cat’s feeding dish. Now, all I’m saying is, who would blow their brains out in the middle of feeding their cat?’

The boy was jerked semi-conscious as they dragged him off the hard bunk. He heard voices around him, the clang of metal doors and the jangling of keys. Sounds echoed in the empty space. A swirl of lights blinded him through his confusion. A sudden lancing pain in his arm made him wince.

It might have been minutes later, or it might have been hours–everything was hazy, unreal. He was vaguely aware of not being able to move, arms pinned behind him. The white light was burning into his head, making him blink and twist his head away as he sat tied in the chair.

He wasn’t alone. Two men were in the cellar with him, watching him.

‘Shall I dispose of him?’ said one voice.

‘No, keep him alive for the moment. He may be useful to us.’
