I should like to see Mrs. King, the cook, again. You said, Mrs. King, that you were awakened by a loud explosion. When you said that, did you mean that it seemed to you to be louder than the second one?”

“Well, sir, it wakened me from my sleep, so it is hard to judge. But it did seem very loud.”

“You don’t think that it might have been two shots fired almost at the same instant?”

“I am sure I couldn’t say, sir.”
