Miss Mount shook her head.
“The shooting degenerated into a romp very soon between the six of them, and ‘Uncle Joel’ came downstairs again in high dudgeon.”
“The six of them?” inquired Bernard.
“Yes, the Grahams had joined the quartette.”
“When?”
“When they all came out of ‘Uncle Joel’s’ room,” Miss Mount explained patiently, “somebody knocked on the Grahams’ door and invited them to go up and shoot, too. I believe it was Isabelle. I heard them all tramp past together.”
“And the next night Mrs. Graham burned her back!” said Bernard suddenly.
Both detectives were aware of a slight stiffening in Miss Mount’s manner. She nodded in silence.
“You went across the hall to investigate, didn’t you?”
“Yes. I heard her scream and knocked on Mr. Graham’s door. The sound came from there.”
