Poison in the Pen [EPUB ebook] 

Miss Silver looked across the tea-tray a good deal in the manner of the affectionate aunt who entertains a deserving nephew, but the young man who leaned forward to take the cup of tea which she had just poured out for him was not really related to her in any way. He was, in fact, Detective Inspector Frank Abbott of Scotland Yard, enjoying a Sunday afternoon off duty and very much at his ease. It would have been difficult to guess his profession. He might have been in the Army, the Navy, or the Foreign Office, he might have been at the Bar. For the rest he wore discreet and beautiful clothes of a most admirable cut, and his tall, slim figure accommodated itself with the ease of long custom to the largest of Miss Silver’s curly walnut chairs, whose spreading laps and carved encircling arms were so much more comfortable than they looked. The cool light eyes set in a pale irregular face softened noticeably as they rested upon his hostess. He admired her—his own word would have been revered. She entertained, she amused, she instructed, she provided his sense of humour with unfailing food, but even in his most irreverent moments he never ceased to feel a profound respect for her.
