“No one at all.”
“What time was it when the interview took place?”
“About a quarter to seven.”
“And none of the clerks were present?”
“No.”
“Now, Lady Rellingham, if I can prove, as I am going to do presently—now just listen, please—if I can prove that that letter was written less than a week before Sir John died, and that during that week there was only one evening on which all of the clerks had gone before seven o’clock, and that on that evening Sir John sent the last one away at half-past six, that must have been the evening the interview took place?”
“Yes, I suppose so.”
“And if that evening was the evening Sir John was murdered, you must have been the last person who saw Sir John alive? Now, Lady Rellingham, I will ask you again, was no one else present at the interview between Sir John and yourself?”
“There was someone else.”
“I thought so. Who was that other person?”
