“What time was it when you reached here again?”
Marden considered for a while.
“I couldn’t say precisely. Sometime round about half-past three or a bit later. I didn’t look at the time.”
“What did you do then?”
“I hunted about for Mr. Foss, but he didn’t seem to be in the house. At last, when I was just giving it up, I met Miss Chacewater coming away from this room, and she told me that Mr. Foss was inside. She went away, and I came to the door. It was half-open and I could hear voices inside: Mr. Foss and Mr. Chacewater from the sound. I thought they’d soon be coming out and that I’d get Mr. Foss as he passed me; so I waited, instead of interrupting them.”
“How long did you wait?”
“Only a minute or two, so far as I can remember.”
“You could hear them talking?”
“I could hear the sound of their voices. I couldn’t hear what they said. There’s an echo or something in this room and all I heard was the tone they were speaking in.”
“What sort of tone do you mean?”
