"I went to my pantry, sir, till Mrs. Twining came."
"How long would that be?"
The butler reflected. "Well, sir, not more than five minutes, I should say, before the front door bell rang."
"When you went to admit Mrs. Twining did you still hear voices in the study?"
"No, sir, not a sound."
"And when you had shown Mrs. Twining on to the terrace — where did you go then?"
"Pardon me, sir, but I did not show Mrs. Twining on to the terrace," said Finch. "Mrs. Twining said that she would announce herself."
"Was that usual?"
"In Mrs. Twining's case, quite usual, sir. Mrs. Twining was a very old friend of Sir Arthur's. She had been motoring in an open car, and she wished to tidy her hair before going on to the terrace. There is a mirror in the hall, as you will notice, sir. Mrs. Twining went to look at herself in it, and told me I need not wait."
"So that you did not see her go out on to the terrace?"
