"St. Argueil? It is about three hours' journey from Paris. Why do you ask?"
"Because I think that I must go there," I answered. "We must try and find out what legal claims Major Delahaye had upon you. What is the name of the Principal?"
"Madame Richard is the lay principal," Isobel answered, "but Sister Ursula is really the head of the place. We girls saw her, though, very seldom—only those who were going to remain," she added, with a little shudder.
"And this Madame Richard," I asked, "is she a kindly sort of a person?"
Isobel shook her head doubtfully.
"I did not like her," she said. "She is very stern. She is not kind to anyone."
"Nevertheless, I suppose she will tell me what she knows," I said. "Give me the Bradshaw, Allan, and that old Continental guide."
I presently became immersed in planning out my route. When at last I looked up, Mabane was working steadily. The others had gone. I looked round the room.
"Where are Arthur and Isobel?" I asked.
He shrugged his shoulders.
