"Do come and look at these pictures, Uncle Peter. I'm sure it's an awfully old book."

Lord Peter Wimsey sighed as he picked his way out of Mr. Ffolliott's dark back shop, strewn with the flotsam and jetsam of many libraries. An unexpected outbreak of measles at Mr. Bultridge's excellent preparatory school, coinciding with the absence of the Duke and Duchess of Denver on the Continent, had saddled his lordship with his ten-year-old nephew, Viscount St. George, more commonly known as Young Jerry, Jerrykins, or Pickled Gherkins. Lord Peter was not one of those born uncles who delight old nurses by their fascinating "way with" children. He succeeded, however, in earning tolerance on honourable terms by treating the young with the same scrupulous politeness which he extended to their elders. He therefore prepared to receive Gherkins's discovery with respect, though a child's taste was not to be trusted, and the book might quite well be some horror of woolly mezzotints or an inferior modern reprint adorned with leprous electros. Nothing much better was really to be expected from the "cheap shelf" exposed to the dust of the street.

"Uncle! there's such a funny man here, with a great long nose and ears and a tail and dogs' heads all over his body. Monstrum hoc Cracoviæ—that's a monster, isn't it? I should jolly well think it was. What's Cracoviæ, Uncle Peter?"

"Oh," said Lord Peter, greatly relieved, "the Cracow monster?" A portrait of that distressing infant certainly argued a respectable antiquity. "Let's have a look. Quite right, it's a very old book—Munster's Cosmographia Universalis. I'm glad you know good stuff when you see it, Gherkins. What's the Cosmographia doing out here, Mr. Ffolliott, at five bob?"

"Well, my lord," said the bookseller, who had followed his customers to the door, "it's in a very bad state, you see; covers loose and nearly all the double-page maps missing. It came in a few weeks ago—dumped in with a collection we bought from a gentleman in Norfolk—you'll find his name in it—Dr. Conyers of Yelsall Manor. Of course, we might keep it and try to make up a complete copy when we get another example. But it's rather out of our line, as you know, classical authors being our speciality. So we just put it out to go for what it would fetch in the status quo, as you might say."

"Oh, look!" broke in Gherkins. "Here's a picture of a man being chopped up in little bits. What does it say about it?"

"I thought you could read Latin."

"Well, but it's all full of sort of pothooks. What do they mean?"

"They're just contractions," said Lord Peter patiently. "'Solent quoque hujus insulæ cultores'—It is the custom of the dwellers in this island, when they see their parents stricken in years and of no further use, to take them down into the market-place and sell them to the cannibals, who kill them and eat them for food. This they do also with younger persons when they fall into any desperate sickness."

"Ha, ha!" said Mr. Ffolliott. "Rather sharp practice on the poor cannibals. They never got anything but tough old joints or diseased meat, eh?"
