A Grave Mistake

PC Dustan looked heavenwards, water was running off his helmet and down his neck, it was dark and he was very cold. Fed up wasn't the half of it. Not that he would have minded being fed up; he was starving. He ducked under the tent flap and started adjusting his collar. In the light of the paraffin lamps half a man was revealed above ground wielding a shovel.
'Tain't right this' he said. 'What tain... err isn't right?' said PC Dunstan.
'All this' said the man 'I digs graves to bury people in, I don't put em in to dig em up agin; it taint right!'
The policeman sighed, the worst of duties and closeted with an old man who had griped since he started digging, if he carried on moaning he'd be staying in that hole. There was the sound of heavy footsteps. He ducked quickly out under the tent flap. The rain had slowed to a drizzle.

DC Colly read the pathologists report. The name Colly would not be flavour of the month for this one. That toe-rag Ransome was going to get away with it, he would have to let him go. He looked through the file and was coming to the conclusion that "you couldn't win them…." when something stopped him in mid cliché.
He found PC Dunstan in the locker room and had a quick word about that night in the rain.
Later that week he explained to his long suffering wife what had happened, 'There I was' he said 'staring down at promotion to traffic division with the answer staring up at me, one of the bloody grave diggers' name was Ransome though he'd tried disguising his signature on the exhumation form'
'Language' said his pained wife…
