He pulled off his spectacles abruptly and put a trembling hand over his eyes.

Mrs Upwater patted his shoulder as if he had been a little boy, “There, there,” she said meaninglessly, and looked at the Saint with tears brimming in her eyes. “Mr Templar, you’re the only man in the world who might be able to do something about a thing like this. You must help us!”

She really didn’t have to plead. For Simon Templar to have walked away from a story like that would have been as improbable a phenomenon as a terrier ignoring the presence of a rat waltzing under his nose. There were people who thought that the Saint was a cold-blooded nemesis of crime, but altogether aside from the irresistible abstract beauty of the situation that the Upwaters had set before him, he felt genuinely sorry for them.

His human sympathy, however, detracted nothing from the delight with which he viewed the immediate future. It was true that only a few hours ago he had promised to be good, but there were limits. His evening, and in fact his whole visit to Amsterdam, was made.

He signaled to a waiter.

“I think we should all have a drink on this,” he said.

The half-incredulous joy in Mrs Upwater’s tear-dimmed eyes, to anyone else, would have been enough reward.

“You will help us?” she said breathlessly.

“There’s nothing I can do tonight. So we might as well just celebrate. But tomorrow,” Simon promised, “I will pay a call on your Mr Jonkheer.”
