that offer a route into Britain for illegal immigrants. I wouldn’t mind checking whether any such colleges exist in and around Bradford on Avon.’
‘What you’re saying is that you wouldn’t mind
‘What a good idea.’
Three-quarters of an hour later came the call he’d been waiting for — from the forensics company conducting the ballistics tests.
‘You wanted the results from the test firing of the G36 rifle found in the river near Avoncliff yesterday.’
‘Don’t I just.’
‘It’s definitely the murder weapon. The bullets discharged in the test-firing chamber have been examined microscopically now and compared with those found at the crime scenes. As you know, the rifling along the sides of the bullets is like a fingerprint, unique to each weapon. The standard is that at least three identical patterns be found. We have better than that.’
‘Nice work.’
‘But …’
‘There’s always a “but” with you people. Tell me, then.’
‘The match is with the used bullets recovered from Wells and Radstock. The bullets from the Bath scene are too deformed to be of any use. However, you did send us a cartridge casing from Bath.’
‘Correct.’
‘Automatic weapons have mechanisms that eject the spent cartridge case and place the new bullet in the firing chamber. The process leaves scratches and marks on the side of the casing that are just as individual, just as reliable.’
Why do scientists always insist on telling you more than you need to know? Impatiently, Diamond said, ‘And?’
‘The casing found in Bath was ejected from a different weapon.’
‘Different? Not a G36?’
‘You’re misunderstanding me. Still a G36, but a different G36.’
‘Are you certain of this?’
‘Totally. We compared the Bath casing with the ones from the test firing and they don’t match. The gun from the river wasn’t used to murder PC Tasker.’
He didn’t spend long brooding on the results. Surprising as they would seem to most of those working on the case, they chimed in with the hypothesis he’d been working towards: two gunmen. Jack Gull had to be brought up to date and so had the rest of the team.
He braved the mockers in the incident room.
Gull’s response was predictable — and satisfying. ‘Why the fuck did they tell you first? I’m the CIO. I’m the head of the Serial Crimes Unit.’
‘I wouldn’t worry about it, Jack,’ Diamond said. ‘No one’s after your job, unless Polehampton is, and they didn’t call him, they called me.’
‘The custody clock is running down. I’m going to have to ask a magistrate for a warrant of further detention.’
‘Yes. Don’t miss out on that.’
‘Ballistics must have got it wrong, anyway,’ Gull said. ‘The sniper won’t have used more than one gun. A gunman treats his weapon like another limb. It’s part of him.’
‘He slung it in the river.’
‘Only when he knew we had him by the short and curlies. It’s got to be the same gun he used for the Walcot Street shooting. Got to be. He’s had it with him ever since.’
Across the incident room, John Leaman looked up and gave Diamond a slight smile. On the first day he’d cautioned Gull against assuming the same gun had been used for all three shootings.
‘Will you take some advice from me?’ Diamond said to Gull.
‘Let’s hear it and I’ll tell you.’
‘Keep things simple. Concentrate on what we know for certain. The gun we found was definitely used for the shootings in Wells and Radstock. It was in the river at Avoncliff where we arrested the guy we’re holding in the cells. We’re confident he’s the sniper.’
‘I know all this. All I want is a fucking confession.’
‘And you won’t get it until you find what language he speaks. Here’s a tip. When I was with him he clearly didn’t understand what I was saying, but when I used the word “consulate”, he went bananas. Some words are the same in different languages, like “le weekend” in French. I think you should look for a language that has the same word for consulate, or consul.’
‘I’m a detective, not a fucking linguist.’
‘Ask a fucking linguist, then.’
Even Jack Gull was forced to grin. ‘It could be one of those words that’s the same in dozens of languages.’
Diamond held up a finger. ‘Yes, but I haven’t finished. Like I said, the mention of the word really upset the suspect. My sense is that he comes from a state that treats its people harshly. He doesn’t want his government getting involved. He’d rather answer to our law than his own.’
‘Are you thinking of the old Soviet bloc? He looks European.’
‘Could be, and I wouldn’t discount the Middle East. Some of those people could easily pass for Europeans.’
‘I’ll give it a whirl. What are you doing next?’
‘I’ve got a funeral to attend.’
But the funeral wasn’t until 3 P.M. Diamond had other lines of enquiry he wasn’t revealing to Gull at this juncture.
‘Guv.’
The quiet, yet insistent, call from across the room was timely. A chance to leave Gull to wrestle with the linguistic problem.
Diamond shimmied between the desks to where Ingeborg was sitting back, adjusting her blonde ponytail, eyes on the computer screen.
‘What is it?’ he asked.
‘You asked me to check private colleges in and around Bradford on Avon. There’s one here known as the West Wiltshire Higher Education Institute. It was under investigation last summer and closed down.’
‘What for?’
‘Enrolling more foreign students than they could possibly cater for. It was an immigration scam. They got accepted for courses, obtained student visas and then disappeared into the underground economy. The government has been trying to crack down. Across the country ninety thousand were taken on last year by educational establishments that don’t have the “highly trusted” status the Ministry of Education is trying to insist on.’
‘When you say “foreign”, you mean from outside the European Union?’
‘Yes. Iraq, Iran, Somalia, Algeria. Shall I go on?’
‘Tell me about this college they shut down. Where was it?’
‘Off the Bath Road at the top of the town. Just a large house as far as I can make out.’
‘You mean Bradford on Avon?’
She nodded. ‘They had capacity for fifty and they enrolled five times that number over the course of a year. They were crafty. They had what they called an induction course that lasted a couple of weeks and then off-site work experience to acquire better language skills. Many of the students couldn’t speak any English when they arrived.’
‘And I suppose the work experience was low-paid casual labour?’
‘You bet. In theory they were supposed to return to study full time when they’d got enough language skills, but they wouldn’t learn much English picking fruit and digging potatoes. You can see why the college lost track of most of them. It was a huge turnover.’
Diamond didn’t need much more persuading. ‘But they’d learn about the local terrain. This is just what I was looking for, Inge, and the best explanation yet for how the sniper might have got to know Becky Addy Wood and
