“That wasn’t mentioned at the inquest!” she exclaimed.
“No,” said Blick. “I didn’t know of the ring’s existence until Miss Valencia Markenmore told me—after the adjournment. She had noticed that her brother was wearing it when he called at the Court before seeing you.”
“And—it was not found on him?”
“It was certainly not found on him.”

“Then—that’s another proof that Harborough killed him!” she exclaimed.
“How?” asked Blick.
“Jealousy! He killed him out of jealousy, and took the ring from him when he was dead—mad with jealousy because Guy had something on him connected with me!”
“You really believe, Mrs. Tretheroe, that Harborough killed Guy Markenmore because he was jealous of him—about you?”
