Mr. Rogers, the man said in a soft, somewhat accented voice at once apologetic and vaguely sardonic, was out, and there were standing orders to admit no one to the workroom during his absence.

There were no dogs in any part of the museum. But if Mr. Jones wished to see Mr. Rogers he might find him just before closing-time.
