“What do you mean by: ‘Just what one might expect?’ ”
“He got some letters every day, sometimes one or two, sometimes half a dozen. Just what one might expect.”
“Have you any idea whether they were business letters or merely private correspondence?”
Marden seemed annoyed by the question.
“How should I know?” he demanded, stiffly. “It’s not my business to pry into my employer’s affairs.”
“It’s your business to read the addresses on the envelopes to see that the postman hasn’t left wrong letters. Did you notice nothing when you did that? Were the addresses mainly typewritten or written by hand?”
“He got bills and advertisements with the address typewritten—like most of us. And one or two letters came addressed by hand.”
“Did you notice the stamps?”
“Some were American, of course.”
