"Listen," he said. "Once upon a time there was a fool, who came back from the War. It was extremely foolish, but then, you see, Patch, he was a fool. Well, after a while he began to feel very lonely. He'd no relations, and what friends he'd had in the old days had disappeared. So he got him a dog--this fool, a little white scrap of a dog with a black patch." The terrier recognized his name and made a dab at the firm chin. "Steady! Well, yes--you're right. It was a great move. For the little white dog was really a fairy prince in disguise--such a pretty disguise--and straightway led the fool into Paradise. Indeed, they were so happy together, the fool and the dog, that, though no work came along, nothing mattered. You see, it was a fool's paradise. That was natural. The result was that one day the fool lifted up his eyes, and there was a great big finger-post, pointing the way they were going. And it said WAY OUT. The dog couldn't read, so it didn't worry him; but the fool could, and fear smote upon his heart. In fact, he got desperate, poor fool. Of course, if he'd had any sense, he'd 've walked slower than ever or even tried to turn round. Instead of that, he ran. Think of it, Patch. _Ran_." The emotion of his speech was infectious, and the terrier began to pant. "Was there ever quite such a fool? And before they knew where they were, the two were without the gates. And there"--the voice became strained, and Lyveden hesitated--"there were ... two paths ... going different ways. And by each path was a notice-board. And one said NO DOGS ALLOWED. And the other said NO FOOLS ALLOWED. And there were only the two paths. Patch ... going different ways...." The approach of a peripatetic tax-collector brought the allegory to an end. Anthony paid for his occupation of the chair in silence, and the collector plodded off at a tangent in the direction of his next quarry. This appearing to be an old lady, he presently altered his course. With a caution bred of experience, he would approach her from behind. A convenient clock struck four, and Lyveden rose to his feet.... Two hours later he descended the area steps of a mansion in Lancaster Gate. The change in his appearance was quite remarkable. The grey suit, soft hat, golf collar and brown shoes, which he had worn in the afternoon, had been put off. In their stead Lyveden was wearing a bowler hat, black boots, a single collar, which stood up uncomfortably all the way round his neck, and a dark blue suit. The latter was clean and had been carefully brushed, but it was manifestly old. Besides, it was obvious that the man who made them had meant the trousers to be worn turned up. Their owner's present disregard of such intention argued his humble respectability. Arrived at the foot of the steps, Anthony thrust a relieving finger between his throat and the collar for the last time, raised his eyes to heaven, and rang the bell.
