'Why don't you shut your gob?' suggested Trotter, digging the gun barrel even deeper into the Fat Man's side.

'Nay, lad, I'm just bringing the constable up to date,' protested Dalziel apparently impervious to either the pain or the danger. 'He ought to know it's not your fault. You're just a victim. You see, Pascoe, Tankie and me are old friends. He were one of the last to be called up only he didn't want to go. Not without reason, either, only when the Queen offers you her shilling, she don't pay much heed to reason. And me, well, I got the job of going and picking him up and making sure he were handed over safe and sound to our colleagues in the military. Full time employment for a while, weren't it, Tankie? Number of times you took off and headed back home! It were regimental punishment at first, which were OK. Then you broke that MP sergeant's nose, and that got you into the glasshouse. Now the thing about glasshouse time, Pascoe, is, it don't count towards your two years' National Service. So if you've got a year left to do when you ' go down for a year, you'll still have a year to do when you come out. Got me?'

'I think I can just about grasp the concept, sir,' said Pascoe with heavy irony.

Dalziel smiled elephantinely.

'Good. I'll make a note of that, constable,' he said softly. And despite all the more immediate and apparently greater dangers, Pascoe felt a shiver go down his spine.

Dalziel resumed.

'So you can see Tankie's problem. The more he hated the army, the wilder he got. But the wilder he got, the longer he had to serve. And the longer he had to serve, the more he hated the army. Had to laugh, some of the tricks he got up to. Burning down the officers' mess! Chucking a grenade under the CO's caravan on an exercise! But they've not got a great sense of humour, the military brass. And that's how Tankie became the Last National Service Man. Right, Tankie?'
