"You nearly passed into trance a little earlier. May I ask whether you heard or saw anything that recalled you?"
Laurie shut his eyes tight in an effort to think. He felt dimly rather proud of himself.
"It was quite short. Then you came back and looked at Lady Laura. Try to remember."
"I remember thinking I had heard a sound."
The medium nodded.
"Just so," he said.
"That would be the third," said Lady Laura, nodding sagely.
"Third what?" said Laurie rather rudely.
No one paid any attention to him.
"Now can you give any account of the last hour and a half?" continued the medium tranquilly.
