Deeder's Lockpick
From The Tales of Deeder Jonathan, by Alain Martel: "This was another remarkable creation of the inestimable Deeder Jonathan, halfling alchemist, seer and moon mage. The incident (as later pieced together from the Greenhollow criminal records) shows that Kelly, Deeder's thievish brother, got "an idea." Kelly's ideas invariably centered about harnessing Deeder's talents to some purely selfish end."
"Kelly told Deeder that he was going to set up as a locksmith, and desired an infallible aid for his craft-- even offering to split the profits (1/10th to Deeder) for the item. The good-natured alchemist took it on as a pet project, and gave Kelly the Lockpick. The latter resolved to try it that evening at a gala affair given to honor a visiting dwarven ambassador."
"But since Deeder had not been told by his brother about the scheme under foot (indeed, he never would have acquiesced) the matter went other than as planned. Suddenly in the middle of the reception a strangely metallic voice rang out, "Kelly, my master! I have detrapped and opened the large oaken chest of Hortel deBankoff! It wasn't easy, you might have had trouble without my assistance!" Instantly guards surrounded Kelly; and had Deeder not pulled all the strings at his disposal his brother might have ended up a foot shorter from his right hand's fingertips in."
"As to Deeder's Lockpick, it vanished after the affair. It has been surmised since that Deeder destroyed it, or Kelly might have secreted it away."
