much of the time. Was this or that fact a genuine fact, or merely a dogmatically expressed opinion masquerading as the one and only truth? Simon saw the irony; he had the Snowmanâs perennially closed mind to thank for his determination to keep his own open.
âHelen Yardley was shot with an M9 Beretta 9 millimetre,â Proust went on. âNot a converted Baikal IZH, as Firearms told us on Monday, nor a 9 millimetre Makarov police gun, as they told us on Tuesday. Since itâs now Wednesday, we have no alternative but to believe them a third time.â
An angry-looking Rick Leckenby stood up. âSir, you forced me to speculate before Iâdââ
âSergeant Leckenby, while youâre on your feet, do you want to tell us a bit about todayâs gun of choice?â
Leckenby turned to face the room. âThe M9 Beretta 9 mil is US army standard issue, and itâs been in circulation since the 1980s, which means it could have come back from Iraq, from the first Gulf War or more recently, or from any other war zone, any time in the last twenty, twenty-five years. Obviously, depending on how long itâs been in the UK, that potentially reduces traceability.â
âSo weâre looking for anyone with links to the American armed forces?â
âOr the British,â said DC Chris Gibbs. âA Brit could have got it off a Yank and brought it back.â
âNo, sir, thatâs the point Iâm trying to make,â Leckenby answered Proust. âIâd say thereâs no grounds for assuming the killerâs got links with the military. If the gun entered the UK in, say, 1990, thereâs a good chance itâs been through several owners since then. What I would say isââ
âDonât tell us what you would say, Sergeant â just say it.â
âThe gun on the streets at the moment, used in more than half of urban shootings, is the Baikal IZH gas pistol. You buy them in Eastern Europe, convert them, and youâve got an effective short-distance murder weapon. My first thought, at the scene, was that since Mrs Yardley was killed at close range, and since Baikals account for the majority of guns weâre seeing lately, and based on the amount of residue on the wall as well as on the body and the carpet around it, the likelihood was that a Baikal killed her. It was only after the bullet was retrieved from her brain and we had a chance to examine it that we were able to link it to the M9 Beretta 9 mil.â
âWhich means what?â Proust asked.
âIt could mean nothing,â said Leckenby. âEither gun, Baikal or Beretta, could theoretically be in the possession of anybody. But my gut feeling is, street shooters donât have M9 Beretta 9 mils. They just donât. So . . . this killerâs as likely to be anybody as he is to be gang-connected or a known offender.â
âHe or she,â a female DC from Rawndesley called out.
âIf the murder weapon is standard US military issue, Sergeant, then weâre going to look for anyone with links to the American army, and, as DC Gibbs sensibly suggests, to our own,â said Proust. When he spoke with this sort of slow deliberation, you were intended to understand that he was taking care not to allow the dam of his disgust to burst. âYouâve no way of knowing how many hands itâs passed through. Guns are like cars, presumably â some sold on every three years, others loyally tended by one careful owner over a lifetime. Yes?â
âI suppose so, sir,â said Leckenby.
âGood. Make sure you have a full resumé of the M9 Beretta, complete with colour pictures, by tomorrow morning, to distribute to everybody,â the Snowman ordered. âAssuming you havenât changed your mind by then and decided the murder weapon was a turbo-charged pea-shooter from the shores of Lake Windermere. Interview teams â youâll need to start
