“My dear fellow, look at me carefully,” he said, “and then if you can conscientiously declare that I show any signs of indulging in stimulants, I’ll give them up altogether.”

Certainly it would have been hard to find a point in which Dick did not present the appearance of perfect health. He had paused, and stood still a moment, his glass in one hand, the whisky-bottle in the other, black against the front of his shirt, and not a tremor of unsteadiness was there. His face of wholesome sun-burnt hue was neither puffy nor emaciated, but firm of flesh and of a wonderful clearness of skin. Clear too was his eye, with eyelids neither baggy nor puckered; he looked indeed a model of condition, hard and fit, as if he was in training for some athletic event. Lithe and active too was his figure, his movements were quick and precise, and even Merwick, with his doctor’s eye, trained to detect any symptom, however slight, in which the drinker must betray himself, was bound to confess that no such was here present. His appearance contradicted it authoritatively, so also did his manner; he met the eye of the man he was talking to without sideway glances; he showed no signs however small, of any disorder of the nerves. Yet Dick was altogether an abnormal fellow; the history he had just been recounting was abnormal, those weeks of depression, followed by the sudden snap in his brain which had apparently removed, as a wet cloth removes a stain, all the memory of his love, and of the cruel bitterness that resulted from it. Abnormal too was his sudden leap into high artistic achievement from a past of very mediocre performance. Why should there then not be a similar abnormality here?

“Yes, I confess you show no sign of taking excessive stimulant,” said Merwick, “but if I attended you professionally—ah, I’m not touting—I should make you give up all stimulant, and go to bed for a month.”

“Why in the name of goodness?” asked Dick.

“Because, theoretically, it must be the best thing you could do. You had a shock, how severe, the misery of those weeks of depression tells you. Well, common-sense says, ‘Go slow after a shock; recoup.’ Instead of which you go very fast indeed and produce. I grant it seems to suit you; you also became suddenly capable of feats which—oh, it’s sheer nonsense, man.”

“What’s sheer nonsense?”

“You are. Professionally, I detest you, because you appear to be an exception to a theory that I am sure must be right. Therefore I have got to explain you away, and at present I can’t.”

“What’s the theory?” asked Dick.

“Well, the treatment of shock first of all. And secondly, that in order to do good work, one ought to eat and drink very little and sleep a lot. How long do you sleep by the way?”

Dick considered.
