Miss Grig's geniality exasperated her because it did not deceive her.
"I'm only asking for information," Miss Grig said with a placatory smile. "I see the copies were delivered at six-thirty in the morning. Who delivered the job?"
"I did."
"Where?"
"At his address. I dropped it into the letter-box on my way home after my night's work. I stayed here because somebody had to stay, and I did the best I could."
"I'm quite sure of that," Miss Grig agreed. "And, of course, you've been paid for all overtime--and there's been quite a good deal. We all do the best we can. At least, I hope so.... And you've never seen Lord Mackworth since?"
"No."
"And you simply dropped the envelope into the letter-box?"
"Yes."
"Didn't see Lord Mackworth that morning?"
