Mrs.Octagon did hate her sister, but she certainly would not risk killing her.

In fact, Jennings examining into the motives and movements of those mentioned, could find no clue to the right person.

He began to believe that the crime had been committed by someone who had not yet appeared--someone whose motive might be found in the past of the dead woman.

Say a member of the Saul family.
But Maraquito was the sole surviving member, and on the face of it was innocent.

As yet Jennings did not know whether Mrs.Herne was her mother, in spite of the resemblance which Susan claimed to have seen.
Also, Caranby said that Maraquito resembled her father, and the features of the Saul family were so strongly marked that it was impossible the elder Saul could have married a woman resembling him.
"Though, to be sure, he might have married a relative," said Jennings, and went to bed more perplexed than ever.
Next day, before calling at the "Shrine of the Muses," he went to Scotland Yard, and there made inquiries about the rumor of false coins being in circulation.
