conversations.value: Nunc Dimittis (short story): When wealthy art collector Lionel Lampson, learns from an unreliable gossip that his younger girlfriend Janet thinks of him, among other things, as a "crashing bore," he devises an elaborate revenge.\nHe visits the artist John Royden and asks him to paint Janet\'s portrait with the stipulation that she does not know who has commissioned it.\nRoyden has an unusual method: he paints his subjects nude and then adds every layer of clothing one at a time.\nWhen the portrait is completed, Lionel (who happens to be skilled at restoring and cleaning paintings) removes all additional layers of paint, exposing Janet without clothing.\nHe then stages a dinner party for Janet and some of society\'s elite, where, at the end of the candle-lit meal, the lights are suddenly turned on and the painting is revealed for all to see.\nLionel leaves the room unobserved (but not before seeing the stunned look on Janet\'s face) and slips away to his house in the country, basking in the success of his scheme until he is called that night by the same old widow who had told him the gossip about Janet and now invites him to pass by; it is then clear to Lionel that she had been hooking him all the time.\nBut things get even worse: a few days later, Lionel receives a container of excellent caviar along with a letter from Janet saying that she forgives him and still loves him.\nLionel feels deeply ashamed.\nNot being able to resist his favorite food, he indulges himself and, by the end of the story, begins to feel violently ill.\nThe implication is that Lionel has been poisoned, perhaps fatally, by Janet.
