Adrian Mulliner, that well known detective about town, does a regular trade guarding the takings at high society weddings. Despite a sudden recurrence of the dyspepsia to which he is a martyr, he recently patrolled a reception where he spoke to a baronet, an OBE, a viscount, a knight and an earl. He smiled his knowing smile (which has been compared to that of DaVinci's Giaconda, or Mona Lisa) while each gentleman was either stuffing his pockets with the silver, cheating at cards, goosing the matron of honor on a crowded dancefloor, switching the gift cards on the wedding gifts, or picking the groom's pocket. Adrian did not actually notice these goings on, but sometimes it's enough merely to be there.
Now Adrian's smile (which he unleashes for medical reasons only, to relieve his dyspepsia) unnerved Allcox, Basingame, Chiswick, Dimplechin and Eggleston so badly that each one immediately took Adrian aside for a confidential chat and to offer him a little gift. Thus Adrian went home richer by a silver cigarette case, a tenner, a fiver, an invitation to Ascot, and a gold Swiss watch.
Being a Mulliner, and thus punctilious to a fault, Adrian wanted to include it all in his report to the father of the bride, but somewhere along the line he lost the little black book in which he was taking notes.
Can you help him sort out which gentleman he met engaged in which activity, the name and title, and what little gift he gave Adrian Mulliner?
