It dawned on the Saint that this vein of dialogue could be continued almost indefinitely, if Mrs Nussberg insisted on it. He looked around somewhat tensely for inspiration, wondering if after all the jewels could be worth the price, and by the mercy of his guardian angel the inspiration was provided.

It was provided in the person of Maurice Walmar, who at that moment came strolling superbly across the lounge and recognized an acquaintance in the far corner. With an elegant wave of his hand he started in that direction. His route took him past the table where Simon was prayerfully groping for the light. Walmar recognized the Spanish Cow, and flashed a mean sneer towards his acquaintance. As he squeezed past the table, he deliberately swerved against Mrs Nussberg’s arm as she raised her glass. The drink spilled heavily across her lap.

“ Pardon,” said Walmar casually, and went on.

Simon leapt up.

Even if he had not been interested in Mrs Nussberg’s jewels, he would probably have done the same thing. He had witnessed every phase of the incident, and at any time he would have called that carrying a joke too far. Nor did he care much for Maurice Walmar, with his too beautifully modeled face and platinum watch bracelet. He caught the young humorist by the elbow and spun him around.

“I don’t think you saw what you did,” he remarked evenly.

For a second the other was startled to incredulity. Then he glanced down at the soaked ruin of Mrs Nussberg’s gown, and back from that to the Saint. His aristocratic lips curled in their most polished insolence.

“I have apologized,” he said carelessly. “It was an accident.”

“Then so is this,” said the Saint mildly, and his fist shot over and slammed crisply into the center of the sneering mouth.

Walmar rocked on his heels. He clutched at a table and went down in a spatter of glass and splashing fluids.
