‘Carn’t hear,’ he blurted.

‘Ah!’ commented the persecutor, raising his eyebrows. ‘Deaf, are you? That’s bad.’ Perceptibly dropping his voice, he studied his victim’s face. ‘H’m—I wonder what degree of deafness. Which is the worst ear?’

With praiseworthy presence of mind, Hagan resisted the impulse to answer. Staring blankly at the ceiling, he made no sign.

Stepping a pace nearer, the officer spoke louder. Hagan still made no voluntary response, but the perspiration upon his face attested to the physical effort.

From the psychological standpoint the doctor was intensely amused. That Private Timothy Hagan was a clumsy malingerer, pure and simple, he had no doubt. To prove such a negative condition however is quite another matter. If proved, the offence meant a court-martial. As an officer it was his duty to conceal no crime which could be proved. He was interested, but had little time just then for fancy cases. Hagan’s facial expression of struggling conjecture condemned him, morally, beyond a doubt, but the production of the self-same expression before the members of a court-martial could hardly be guaranteed.

It was a six-inch German shell that solved the situation for the moment. Dropping three hundred yards from the dressing-station in the middle of the village street it exploded with a roar which smashed every pane of glass in the building. A second quickly followed. The R.A.M.C. staff, expectant of they knew not what, stood listening. Hagan, feeling the eyes of the medical officer upon him, did not move a muscle.

‘One to you,’ murmured the officer to himself. ‘I don’t believe a word of it all the same.’ Turning on his heel, he winked to the orderly and with well-assumed indifference strode to the far end of the room.

The orderly, quickly stepping round to the head of Hagan’s stretcher, needed no further instructions. With book and pencil in hand, he appeared to be engaged upon his ordinary duty of taking names for the Clearing Hospital.

‘What’s your number, matey?’ he asked quickly.

The wretched competitor, breathing heavily after his recent mental tension, had dropped his guard.
