It was about the same time that Simon realized, from the frequent glances in his direction, that he was somehow being made a major factor in the discussion.

He gazed out of the window at the twinkling lights reflected in the ornamental lakes of the Vondel Park and hoped that his impression was mistaken, or that they would soon find something else to argue about.

A voice at his elbow said, “Excuse me, Mr Templar — you are the Saint, aren’t you?”

He turned resignedly. It was the woman, of course.

“I suppose somebody told you at the Hollandia,” he said. “But they should have told you not to worry. I’ve promised not to murder anyone or steal their jewels while I’m here.”

“My name’s Upwater,” she said. “And I did want to talk to you about jewels. But not about your stealing them. I’ve heard that you’re really a good man, and you help people in trouble, and we’re in terrible trouble. I told my husband it seemed like Providence, your being here, just when this awful thing has happened. I said, ‘The Saint’s the only person who might be able to help us,’ and he said, ‘Why should you bother?’ and we had quite an argument, but I had to speak to you anyway. At least you’ll listen, won’t you? May I call him over?”

She had already dumped herself in a vacant chair, and the Saint did not see any way short of outright churlishness to dislodge her. In the mellow aftermath of a good meal, such violent measures were unthinkable. And he had nothing else in particular to do. That was so often what got him into things...

He grinned philosophically, and nodded.

“What’s the matter with these jewels?” he inquired.

She turned and beckoned to her husband, who started to get up from their table, looking more worried than ever.
