"Dr. Sardon likes Dr.ess clothes even less than you do. And you never warned me that you were coming here at all. So what could I do? I accepted his invitation a week ago, so when you arrived I could only tell Sardon what had happened. Of course he insisted that you must come with me. But I think he will interest you."

The Saint sighed resignedly and swished the highball gently around in his glass so that the ice clinked.

"Why should I be interested in any of your neighbours?" he protested. "I didn't come here to commit any crimes; and I'm sure all these people are as respectable as millionaires can be."

"Dr. Sardon is not a millionaire. He is a very brilliant biologist."

"What else makes him interesting?"

"He is very fond of ants," said Nordsten seriously, and the Saint sat up.

Then he finished his Dr.ink deliberately and put down the glass.

"Now I know that this climate doesn't agree with you," he said. "Let's get changed and go down to the tennis court. I'll put you in your place before we start the evening."

Nevertheless he Dr.ove over to Dr. Sardon's house that evening in a mood of open-minded curiosity. Scientists he had known before, men who went down thousands of feet into the sea to look at globigerina ooze and men who devised complicated electrical gadgets in laboratories to manufacture gold; but this was the first time that he had heard of a biologist who was fon,d of ants. Everything that was out of the ordinary was prospective material for the Saint. It must be admitted that in simplifying his own career to elementary equations by which obvious excrescences on the human race could be soaked, he did himself less than justice.

But there was nothing about the square smooth-shaven man who was introduced to him as Dr. Sardon to take away the breath of any hardened outlaw. He might perhaps have been an ordinary efficient doctor, possibly with an exclusive and sophisticated practice; more probably he could have been a successful stockbroker, or the manager of any profitable commercial business. He shook hands with them briskly and almost mechanically, seeming to summarize the Saint in one sweeping glance through his crisp-looking rimless pince-nez.
