“Oh, wait a bit! What was to prevent Sir John having arranged a meeting between the two of them there in his presence, to make arrangements about calling the trust into operation, if it were ever necessary? Let’s assume he did. Assume they met there, which of them would be the more likely to shoot him?”
“The daughter,” said Marston.
“Why do you think that?”
“She murdered him and then committed suicide.”
Tempest shook his head. “No, I think you are wrong. The mother shot Sir John in the presence of her daughter; then she murders the daughter as well, to cover up the disclosure. Voila tout. There you have a complete explanation—a logical explanation, and a sufficient one for both murders.”
“Tempest, I believe you’ve hit it.”
“I may have done; but it’s all pure guesswork. It won’t hang her.”
“How did she put the revolver in my suit-case?”
“God knows, old man! That I fancy will always be a mystery. When was the revolver put there?”
“I wish I knew.”
