Some years before, the brothers had had a series of telescopic, lead-weighted, fighting batons designed and made for them. Eight inches long, the batons fitted comfortably inside the forearm sleeve of a jacket, where they were secured in place by the simple expedient of a loop and a double button.
Although principally made of rubber, the batons were not able to pass through a metal detector by dint of their lead content, and therefore had to be transported separately on an aeroplane as part of hold baggage – or secreted, for instance, inside a travelling fishing-rod case, where they could be passed off as fisherman’s priests. By train and by car, however, they were perfection itself. Once liberated from their housings, the batons extended with a simple flick of the wrist to a total of two feet in length, retaining more than enough rigidity to guarantee a quite remarkable hand-to-target action.
They would kill, of course, if used aggressively, but their principal function was defensive – they were designed as pacifiers. In ten seconds a man could be crippled, his legs worse than useless, by the simple expedient of a scything stroke behind the knee. The twins, being two, found this the best resort in all but the most extreme of circumstances. One would monopolize the target’s attention whilst the other struck him from behind. It had never failed them. A frightened man on the floor, one leg unmarked but useless, was a very different animal indeed from an angry man in possession of all his physical faculties.
The inspector curled up in the foetal position at the entrance to his apartment and began to dry retch, like a cat attempting to bring up a fur ball. His wife came hurrying out of the kitchen, where she had been preparing their supper. Vau gave her two for good measure, one behind each knee. She dropped to the floor and then stretched out, like a postulant at some Easter confraternity ceremony.
Abi closed the door. He and Vau dragged the couple through into the lounge.
Vau switched on the television. ‘Gas explosion or double suicide?’
The inspector tried to raise himself from the floor. Vau flailed him behind the other knee. ‘Silence. You will both remain silent, faces to the ground. Do you understand me?’
The woman was unconscious – shock, probably. The boys were used to people responding in disparate ways. Women were particularly vulnerable to sudden explosions of violence, whereas men would often struggle, requiring further pacification.
Abi snapped his fingers triumphantly. ‘No. No. Listen. I’ve got another idea. Kill two birds with one stone.’
‘How’s that?’
‘Wait for me here. I won’t be more than ten minutes. A surprise.’ Abi was staring out of the window now, his expression speculative. He snapped the baton shut and secreted it back inside his sleeve. He had scarcely even broken into a sweat.
