"I mustn't stay," she continued. "This is what I wanted to tell you. As I was crossing the square just now, I recognised the man Frenhofer, from the Villa Mimosa. Directly he saw me he came across the road. He was looking for one of us. He dared not come to the villa, he declares, for fear of being watched. He has something to tell you."

"Where can I find him?" Hunterleys asked.

"He has gone to a little bar in the Rue de Chaussures, the Bar de Montmartre it is called. He is waiting there for you now."

"You must stay and have some lunch," Hunterleys begged. "I will come back."

She shook her head.

"I have just been across to the Opera House," she explained, "to enquire about some properties for to-night. I have had all the lunch I want and I am on my way to the hospital now again. I came here on the chance of finding you. They told me at the Hotel de Paris that you were lunching out."

Hunterleys turned and whispered to Simpson.

"This is very important," he said. "It concerns the affair in which we are interested. Linger over your coffee and I will return."

Mr. Simpson nodded and Hunterleys left the restaurant with Felicia. His wife, at whom he glanced for a moment, kept her head averted. She was whispering in the ear of the gallant Monsieur Douaille. Selingman, catching Draconmeyer's eye, winked at him solemnly.

"You have all the luck, my silent friend," he murmured.
