"Boy, that's marvellous!" breathed Patricia dreamily. "You know that military sort of coat of mine, the one with the brass buttons? We were wanting to get them chromed —"

The Saint sighed.

"And that," he said, "is approximately what the cave woman thought of first when her battle-scarred Man dragged home a vanquished leopard. My darling, when will you realize that we are first and foremost a business organization?"

But at that moment he had no clear idea of the profitable purposes to which his purchase might be put. The Saint had an instinct and a collecting passion for facts and gadgets that "might come in useful," but at the times when he acquired them he could rarely have told you what use they were ever likely to be.

He corked the bottle and put it away in his pocket. The train they were waiting for was signalled, and the rumble of its approach could be felt underfoot. Down in the blackness of the tunnel its lights swept round a bend and drove towards the platform; and it was quite by chance that the Saint's wandering glance flickered over the shabbily-dressed elderly man who waited a yard away on his left, and fixed on him with a sudden razor-edged intentness that was more intuitive than logical. Or perhaps the elderly man's agitation was too transparent to be ordinary, his eyes too strained and haggard to be reassuring… Simon didn't know.

The leading draught of the train fanned on his face, and then the elderly man clenched his fists and jumped. A woman screamed.

"You blithering idiot!" snapped the Saint, and jumped also.

His feet touched down neatly inside the track. By some brilliant fluke the shabby man's blind leap had missed the live rail, and he was simply cowering where he had landed with one arm covering his eyes. The train was hardly more than a yard away when the Saint picked him up and heaved him back on to the platform, flinging himself off the line in the opposite direction as he did so. The train whisked so close to him that it brushed his sleeve, and squeaked to a standstill with hissing brakes.

The Saint slid back the nearest door on his side, swung himself up from the track, and stepped through the coach to the platform. A small crowd had gathered around the object of his somewhat sensational rescue, and Simon shouldered a path through them unceremoniously. He knew that one of the many sublimely intelligent laws of England ordains that any person who attempts to take his own life shall, if he survives, be prosecuted and at the discretion of the Law imprisoned, in order that he may be helped to see that life is, after all, a very jolly business and thoroughly worth living; and such a flagrant case as the one that Simon had just witnessed seemed to call for some distinctly prompt initiative.

"How d'you feel, chum?" asked the Saint, dropping on one knee beside the man.
