Somerfield looked at her in an aggrieved fashion.

“Well,” he said, “I thought that this was to be an amusing luncheon party.”

“You should have talked more to Lady Grace,” she answered. “I am sure that she is quite ready to believe that you are perfection, and the English army the one invincible institution in the world. You mustn’t take me too seriously today, Charlie. I have a headache, and I think that it has made me dull.”...

They trooped out into the foyer in irregular fashion to take their coffee. The Prince and Penelope were side by side.

“What I like about your restaurant life,” the Prince said, “is the strange mixture of classes which it everywhere reveals.”

“Those two, for instance,” Penelope said, and then stopped short.

The Prince followed her slight gesture. Inspector Jacks and Dr. Spencer Whiles were certainly just a little out of accord with their surroundings. The detective’s clothes were too new and his companion’s too old. The doctor’s clothes indeed were as shabby as his waiting room, and he sat where the sunlight was merciless.

“How singular,” the Prince remarked with a smile, “that you should have pointed those two men out! One of them I know, and, if you will excuse me for a moment, I should like to speak to him.”

Penelope was not capable of any immediate answer. The Prince, with a kindly and yet gracious smile, walked over to Inspector Jacks, who rose at once to his feet.

“I hope you have quite recovered, Mr. Inspector,” the Prince said, holding out his hand in friendly fashion. “I have felt very guilty over your indisposition. I am sure that I keep my rooms too close for English people.”
