...of a silencer

General Tedeki started to speak. But then a tremendous clatter at the office door; he ceased. The door swung open.
Two burly white men appeared, both armed with pistols equipped with silencers. They made out Mr Baynes.
‘Da ist er,’ one said. They started for Mr Baynes.
At his desk, Mr Tagomi pointed his Colt ’44 ancient collector’s item and compressed the trigger. One of the S.D. men fell to the floor. The other whipped his silencer-equipped gun towards Mr Tagomi and returned fire. Mr Tagomi heard no report, saw only a tiny wisp of smoke from the gun, heard the whistle of a slug passing near. With record-eclipsing speed he fanned the hammer of the single action Colt, firing it again and again.
